In a small bowl, mash black beans. Stir in the onion, yellow pepper, chili powder and cumin. In another bowl, combine the tomatoes, jalapeno and garlic.
Place crust on an ungreased 12-in. pizza pan; spread with bean mixture. Top with tomato mixture and spinach. Sprinkle with cilantro, pepper sauce, cheddar cheese and pepper Jack cheese.
Bake at 400° for 12-15 minutes or until cheese is melted.
