2cupsFeta cheeseoptional (you have to try this in your burritos at least once; it's an amazing addition)
Mash the black beans slightly with a fork.
Add them to a microwave-safe bowl along with the corn, rice, onions, peppers, and black olives.
In a separate bowl, combine rice vinegar, oil, chiles, garlic, chili powder, cumin, and hot pepper sauce; whisk together until well blended.
Add to bean mixture; stir to coat and microwave for 3-5 minutes or until hot throughout.
Add cilantro to the hot bean mixture; toss gently.
Place a tablespoon or so of salsa in the middle of a tortilla and top with ranch dressing or sour cream. Use a spoon to spread them out a bit.
To make burritos you can pick up and eat, spoon about 1/3 cup of bean mixture into the center of a tortilla. To make burritos that you eat with a fork, spoon about 1/2 cup of bean mixture into the tortilla.
Sprinkle generously with shredded cheese and feta, roll up, and serve.
