In 10- or 12-inch nonstick skillet, cook 1 lb lean ground beef and 1 finely chopped garlic clove over medium-high heat 5 to 7 minutes, stirring occasionally, until thoroughly cooked. Drain. Stir in half of the 4 oz quartered pepperoni slices and 1 cup of the pizza sauce. Cook 5 minutes or until mixture is thoroughly heated. Remove from heat.
