If your lunch routine is stuck on repeat, this Mexican tuna salad recipe is here to shake things up. Canned tuna gets a bold Tex-Mex makeover with black beans, sweet corn, juicy tomato, creamy avocado, and a zesty chili lime dressing — no stove required. It comes together in 15 minutes flat and tastes anything but ordinary.

What makes this Mexican tuna salad healthy?
This healthy Mexican tuna salad brings a lot to the table. Tuna and black beans team up for a serious protein boost that keeps you full all afternoon, and the beans add fiber too. Crunchy bell pepper, tomato, red onion, and fresh cilantro pack in vitamins and bright flavor, and avocado brings creamy, heart-friendly fats. The dressing keeps things light with just a few spoonfuls of mayo and sour cream — swap in plain Greek yogurt for a high protein tuna salad that works for meal prep, low-carb lunches, and everything in between.

TIPS AND FREQUENTLY ASKED QUESTIONS
Read on for tips and substitution ideas on how to make this recipe, such as how to customize this salad, and how to store this salad.
How long does Mexican tuna salad last in the fridge?
Store leftovers in an airtight container in the refrigerator for up to 2 days. The avocado is the limiting factor here — a squeeze of extra lime juice over the top helps keep it fresh and green. Give it a gentle stir before serving.
Can I make this tuna salad without mayonnaise?
Yes! Swap the mayo for plain Greek yogurt for a lighter, higher-protein dressing. Mashed avocado works too and doubles down on the creamy factor.
Is this Mexican tuna salad spicy?
It’s mild as written. The jalapeño is seeded, which removes most of the heat, and you can skip it altogether. Want more kick? Leave some seeds in or add a few dashes of your favorite hot sauce.
What should I serve with Mexican tuna salad?
Tortilla chips are the classic move, and lettuce wraps make it a great low-carb lunch. Try it piled onto tostadas, stuffed into avocado halves, tucked into a sandwich or wrap, or spooned over a bed of greens.
Can I meal prep this recipe?
Yes — with one trick. Mix everything except the avocado and store it in the fridge, then dice and fold in the avocado just before eating. The flavors get even better after an hour or two of chilling.
There you have it — a Mexican tuna salad that turns a handful of pantry staples into the lunch you’ll be craving all week.
