Heat oven to 400°F. To thaw biscuits, place on microwave-safe plate; microwave on High for 15 to 30 seconds or until biscuits are soft enough to press into rounds.
Place biscuits on ungreased cookie sheet. Press or roll each to form 6-inch round. Spread 1 teaspoon salad dressing on each round. Top each evenly with all remaining ingredients.
Bake at 400°F. for 13 to 15 minutes or until crust is golden brown and cheese is melted.
