Philly Cheese and Ground Beef Casserole

Such a great recipe. I think the biscuits are really what makes this dish.

1	lb 93/7 lean ground beef
1	package (8 oz) sliced mushrooms
1	teaspoon salt
1/2	teaspoon pepper
8	slices (1 oz each) provolone cheese
2	tablespoons butter or margarine
1	large onions, halved and thinly sliced into wedges
1	medium red bell peppers, cut into strips
2	cloves garlic, finely chopped
1	can (16.3 oz) Pillsbury® Grands!® Homestyle original biscuits

	Heat oven to 350°F. Spray 11x7-inch baking dish with cooking spray.
	In 12-inch skillet, cook beef, mushrooms, salt and pepper over medium-high heat 7 to 9 minutes, stirring frequently, until beef is thoroughly cooked; drain. Place in baking dish. Arrange cheese over beef mixture, overlapping slices if needed. Meanwhile in a separate skillet, melt butter over medium-high heat. Add onions and bell peppers. Cook over medium-high heat 3 to 5 minutes, stirring frequently, until peppers are crisp-tender. Stir in garlic; cook 1 to 2 minutes longer. Spoon over cheese in baking dish.
	Separate dough into 8 biscuits. On lightly floured surface, pat biscuits into 5-inch circles. Arrange biscuits over vegetable mixture.
	Bake 20 minutes or until biscuits are golden brown on top. Makes 8 servings
