Corn and Bean Salsa

This is my own and it's super easy! Combine one can corn, one cup black beans, diced tomatoes, diced onions, chopped cilantro, 2 tbsp olive oil, 1-2 tsp chili powder, fresh lemon juice from half a lemon, half teaspoon ground oregano, salt and pepper.  Voila!  You can have it as a salsa side, or add chopped red leaf lettuce for a salad.
