What Goes Into a Keto Mediterranean Garlic Tuna Salad with Jalapeño Coleslaw

This is a two-part recipe — the Mediterranean tuna salad and the jalapeño coleslaw — and both are low effort, high reward on their own. Together? Absolute magic.

The Mediterranean Garlic Tuna Salad

Pro tip: Use tuna packed in olive oil, not water. Trust me on this one — the flavor difference is significant, and it keeps the salad from feeling dry.

The Jalapeño Coleslaw

“The jalapeño coleslaw isn't just a side — it's the texture and heat contrast that makes this whole dish sing.”

Fair warning: if you're sensitive to heat, start with one jalapeño. The seeds carry most of the fire, so deseed them for a milder version. No judgment here either way.

How to Make Keto Mediterranean Garlic Tuna Salad with Jalapeño Coleslaw

Spoiler alert — this is genuinely one of the easiest recipes in the rotation. Here's how it comes together:

Step 1: Make the Jalapeño Coleslaw First

Start with the coleslaw so it has time to marinate while you prep the tuna.

1. Combine shredded green cabbage, purple cabbage, carrots, and jalapeño slices in a large bowl.
2. Whisk together mayo, apple cider vinegar, celery seed, salt, and pepper in a small bowl.
3. Pour dressing over the slaw and toss well to coat.
4. Set aside — even 10 minutes of rest makes it better.

Step 2: Build the Mediterranean Tuna Salad

1. Drain the tuna and flake it into a medium bowl — keep some larger chunks for texture.
2. Add minced garlic, halved olives, capers, and chopped sun-dried tomatoes.
3. Whisk olive oil, lemon juice, and Dijon mustard together, then pour over the tuna mixture.
4. Fold in fresh parsley, season with salt and pepper, and taste. Adjust lemon or garlic as needed.

Step 3: Serve It Right

Two ways to plate this:

• Bowl style: Pile the jalapeño coleslaw in the base of a wide bowl and spoon the garlic tuna salad on top.
• Side by side: Serve both components separately and let people build their own ratio. Crowd-pleaser alert for family meals. 🙌

Storage, Meal Prep, and Smart Swaps

Meal prep magic: Both components store separately in airtight containers in the fridge for up to 3–4 days. The coleslaw actually gets better on day two as the flavors meld. Future you will thank you.

Smart swaps to know:

• No kalamata olives? Green olives or castelvetrano olives work beautifully.
• Watching sodium? Rinse the capers before adding them.
• Want more protein? Add a soft-boiled egg on top.
• Dairy-free? This recipe already is — you're good.
• No jalapeños? Serrano peppers bring similar heat; banana peppers keep it mild.
