Place drained tuna in a medium mixing bowl and mix with a fork to break up large pieces.
Add chopped red pepper, red onion, corn and black beans (rinsed and drained), mayo, cilantro, cumin, jalapeno and lime juice.
Mix with a fork.
Serve immediately or place in an airtight container and store in the fridge for up to 48 hours.
Notes
Any type of canned tuna will work: albacore, light chunk, yellowfin or skipjack. Make sure your tuna is drained or the salad may turn watery. I usually open the can, pour the contents onto a sieve and let it drain while I chop the veggies.Add as much or as little mayo as you like. If you prefer a creamy tuna salad, increase the amount of mayo to ⅓ or even ½ cup. You can also swap some or all of the mayo with plain Greek yogurt.If you're looking for more spice, as a whole jalapeno instead of ½. You can also add ½ teaspoon of cayenne pepper.
