Preheat oven to 375°F.
In a medium nonstick skillet, brown ground meat.
Meanwhile, prepare frozen mashed potatoes according to package directions. When potatoes are cooked, stir in garlic.
Spray a 2-quart casserole dish with no-stick spray; add browned meat and pasta sauce. Spread mashed potatoes over top of meat mixture.
Bake 35 to 40 minutes, or until mashed potatoes begin to brown.
