In a large skillet coated with cooking spray, saute peppers and onions until crisp-tender. Stir in the mushrooms, water, broth and garlic. Bring to a boil. Reduce heat; simmer, uncovered, for 8-10 minutes or until vegetables are tender and liquid has evaporated.
Stir in the beans, salsa, chili powder and pepper sauce; heat through.
Spoon 1 cup filling off-center on each tortilla. Sprinkle with cheese. Fold sides and ends over filling and roll up.
