What Goes Into This Recipe – Ingredients
- For the Mediterranean Garlic Tuna:
- 2 cans (5 oz each) tuna, drained (oil-packed for richer flavor or water-packed for lighter)

- 1 tbsp capers, drained and chopped
- 1/4 cup red onion, finely diced
- 1/4 cup cucumber, finely diced
- 2 tbsp fresh parsley, chopped
- 1 tbsp fresh dill, chopped (optional but excellent)
- Zest of 1/2 lemon + 1–2 tsp fresh lemon juice
- 1/4 tsp dried oregano
- Salt and black pepper to taste
- For the Jalapeño Coleslaw:
- 3 cups shredded cabbage (green, purple, or a mix)
- 1 small jalapeño, thinly sliced (seeds removed for less heat)
- 1/4 cup scallions, thinly sliced
- 2 tbsp mayonnaise
- 1 tbsp sour cream or Greek-style keto yogurt
- 1 tbsp apple cider vinegar
- 1/2 tsp Dijon mustard

Let's Get Cooking – Instructions
- Prep the slaw base: In a large bowl, combine cabbage, jalapeño, and scallions. Keep it dry for now so it stays crunchy.
- Whisk the slaw dressing: In a small bowl, whisk mayonnaise, sour cream, apple cider vinegar, Dijon, celery seed, salt, and pepper until smooth.
- Toss and chill: Pour dressing over the cabbage mixture. Toss until everything’s lightly coated.
Taste and adjust salt and acid. Chill in the fridge while you make the tuna.
- Mix the tuna dressing: In a medium bowl, combine olive oil, mayonnaise, garlic, lemon zest, lemon juice, oregano, and a pinch of salt and pepper.
- Build the tuna salad: Add drained tuna, capers, red onion, cucumber, parsley, and dill. Fold gently until the mixture is cohesive but not mushy.
Taste and tweak seasoning.
- Assemble: Plate a scoop of jalapeño coleslaw and top with a mound of Mediterranean garlic tuna. Add avocado, olives, and an extra squeeze of lemon if you’re feeling fancy.
- Serve: Eat immediately for max crunch, or pack for lunch. It’s excellent cold.
Preservation Guide
- Fridge: Store tuna and coleslaw in separate airtight containers for 3–4 days.
The slaw keeps its bite longer when undressed; if prepping ahead, dress it the day you eat it.
- Make-ahead hack: Mix all tuna components except cucumber and herbs. Stir those in just before serving to keep it bright and crisp.
- Freezer: Do not freeze. Mayo-based salads and fresh cabbage don’t thaw well.
Texture gets weird, and not in a fun way.
- Transport: Keep chilled with an ice pack. Assemble at lunchtime for the freshest texture.
Benefits of This Recipe
- Keto-friendly: Minimal carbs, high in quality fats and protein. Keeps you in the zone without boredom.
- Omega-3 rich: Tuna brings EPA/DHA for brain health, mood, and inflammation balance.
Your neurons will send thank-you notes.
- Gut-friendly crunch: Cabbage provides fiber to keep digestion moving, even on keto.
- Metabolism-friendly heat: Jalapeño adds capsaicin, which may offer a small metabolic bump. Plus, it tastes like confidence.
- Budget and time efficient: Pantry staples + 20 minutes = lunch hero status.
Pitfalls to Watch Out For
- Watery slaw: Overdressing early can lead to pooling. If making ahead, dress closer to serving or salt the cabbage, rest 10 minutes, then pat dry before dressing.
- Too much lemon or vinegar: Acid is great until it’s not.
Add gradually and taste as you go.
- Overmixing tuna: Gentle folds keep texture. You’re making salad, not tuna paste.
- Hidden sugars: Some mustards, yogurts, or mayo sneak in carbs. Read labels, IMO.
- Jalapeño heat level: Seeds carry the fire.
Remove if you’re spice-sensitive; add extra if you’re chaos-friendly.
Mix It Up
- Protein swap: Use canned salmon or shredded rotisserie chicken with the same seasoning profile.
- Herb twist: Swap dill for mint or basil. Each changes the vibe from seaside taverna to summer garden.
- Crunch upgrades: Add toasted sliced almonds, pumpkin seeds, or crushed pork rinds for extra texture.
- Creamy upgrade: Stir a spoon of tahini into the tuna dressing for nutty depth.
- Serve creatively: Spoon into avocado halves, wrap in butter lettuce, or pile over a bed of arugula with olive drizzle.
- Extra heat: Add a pinch of Aleppo pepper or red pepper flakes to the tuna.
FAQ
Can I use fresh tuna instead of canned?
Yes. Sear a tuna steak to medium-rare, chill, then flake or dice and mix as directed.
It’s exceptional, but canned is more budget-friendly and still delicious.
Is this recipe dairy-free?
It can be. Use dairy-free mayo and replace sour cream with extra mayo or a coconut-based alternative. The flavor remains bold and balanced.
How spicy is the jalapeño coleslaw?
Mild to medium.
Removing seeds and membranes lowers the heat. Want more kick? Add a second jalapeño or a dash of hot sauce.
What can I use instead of capers?
Chopped green olives or a tiny splash of olive brine deliver similar salty, briny brightness.
Anchovy paste (1/4 tsp) also works if you’re adventurous.
Will this kick me out of ketosis?
Very unlikely if you stick to the listed ingredients and portions. It’s predominantly protein and fats with minimal net carbs from vegetables.
Can I make it without mayo?
Yes. Use olive oil plus a tablespoon of tahini or mashed avocado for creaminess.
It’s still rich and silky, FYI.
How do I reduce the fishy taste?
Use high-quality tuna (pole-caught or ventresca if possible), drain well, and lean into lemon, herbs, and capers. Oil-packed tuna tends to taste richer and less “tinny.”
My Take
This Keto Mediterranean Garlic Tuna Salad With Jalapeño Coleslaw punches way above its weight class. It’s fast, clean, and engineered for flavor without the carb baggage.
The briny, herby tuna and crisp, spicy slaw feel like a chef move—even though it’s weeknight easy. Keep a few cans of tuna and a head of cabbage on standby, and you’ve got a go-to meal that never phones it in. Honestly, if every “healthy” lunch tasted like this, we’d all be eating better and bragging about it, too.
