Preparation
HEAT oven to 425°F. Crumple 4 large sheets of foil to make 4 (3-inch) balls; place on baking sheet. Place 1 tortilla over each ball; spray with cooking spray. Bake 6 to 8 min. or until tortillas are golden brown. (Tortillas will drape over balls as they bake.)
MEANWHILE, brown meat with chili powder in large nonstick skillet on medium-high heat, stirring occasionally. Add salsa and beans; cook 5 min. or until heated through, stirring occasionally.
PLACE 1 tortilla shell on each of 4 serving plates. Fill with salad greens, meat mixture, cheese and tomatoes. Top with dressing.
