PREHEAT oven to 350°F. Microwave tortillas on HIGH 30 sec. or until softened. Press 1 tortilla into each of eight medium muffin cups to form a bowl. Carefully fold edges of tortilla back to keep an opening for the filling. Bake 10 min.

MEANWHILE, brown meat in large skillet on medium heat; drain. Stir in salsa; bring to boil. Reduce heat to medium-low; simmer 10 min. Spoon about 1/4 cup of the meat mixture into each tortilla bowl.

TOP evenly with cheese, lettuce and tomatoes. Drizzle with dressing.
