Ingredients

Here’s what you’ll need to build the perfect Mexican Tuna Salad:

• 2–3 cans (5 oz each) tuna, drained well (Wild-caught canned tuna is a great pantry staple to keep on hand)
• ¼ cup mayonnaise (or Greek yogurt, or mashed avocado)
• Juice of 1 fresh lime
• 1 Roma tomato, diced
• ¼ cup finely diced red or white onion
• 2 tablespoons fresh cilantro, chopped
• 1–2 tablespoons diced jalapeño or serrano pepper (adjust to taste)
• ¼ cup canned corn, drained (optional but recommended)
• Salt and pepper to taste
• ¼ teaspoon cumin or chili powder (optional)

Optional add-ins for extra texture:

• Diced cucumber
• Diced celery
• Black beans
• Diced avocado

How It Comes Together

This recipe is incredibly forgiving and easy—think of it as mixing and tasting as you go.

• Start by draining your tuna really well. This makes all the difference. Excess liquid will water down the flavor and texture. Add the tuna to a medium mixing bowl and gently break it apart with a fork.
• Add your mayonnaise, fresh lime juice, cumin, salt, and pepper. Stir until everything is evenly coated. The lime is what gives this salad its signature bright flavor—don’t skip it.
• Now fold in the good stuff: tomatoes, onion, cilantro, jalapeño, and corn. Mix gently so the tuna stays flaky and not mashed.
• Taste and adjust seasoning. You might want a little more lime, salt, or heat depending on your preference.
• Cover and refrigerate for 15–30 minutes. This step helps the flavors come together beautifully.
• Serve chilled and garnish with avocado, extra cilantro, or another squeeze of lime.

Serving Suggestions

Tips for the Best Flavor

• Fresh lime juice is essential. It transforms the entire dish.
