Cooking spray
2 C. vertically sliced onion
1 (8-oz.) package presliced mushrooms
3/4 tsp. salt, divided
1 (8-oz.) boneless sirloin steak, trimmed
1/4 tsp. coarsely ground black pepper
3 (7-inch) refrigerated individual pizza crusts (such as Mama Mary’s)
2 T. low-fat mayonnaise
1 1/2 tsp. prepared horseradish
1/3 C. (about 1 1/2 oz.) crumbled blue cheese

Preheat oven to 450�. Heat a large nonstick skillet coated with cooking spray over medium-high heat. Add onion and mushrooms; cover and cook 3 minutes. Uncover and cook 5 minutes, stirring occasionally. Stir in 1/4 tsp. salt; remove onion mixture from pan. Sprinkle steak with 1/2 tsp. salt and pepper. Add steak to pan; cook over medium-high heat 3 minutes on each side or until desired degree of doneness. Let stand 5 minutes; cut steak diagonally across grain into thin slices. Place crusts on a baking sheet. Bake at 450� for 3 minutes. Remove crusts from oven. Combine mayonnaise and horseradish; spread each crust with about 2 tsp. mayonnaise mixture. Arrange onion mixture evenly over crusts; bake at 450� for 2 minutes. Divide steak and cheese evenly among pizzas; bake an additional 2 minutes or until cheese melts. Cut each pizza in half.
