Beef Stroganoff

1 pound lean ground beef (ground pork works well, too)
1 tablespoon minced garlic
1/2 cup frozen chopped onion
1 can mushroom stems & pieces, drained
1 16 oz container fat-free sour cream
1 cup water
4 tablespoons all-purpose flour
4 teaspoons beef bouillon granules
1/4 teaspoon black pepper
4 cups cooked egg noodles or rice

In a large skillet, brown beef with garlic & onion. Add mushrooms. Meanwhile, stir together sour cream, water, flour, bouillon, and pepper. Once beef is cooked through, add sour cream mixture. Cook and stir until thickened and bubbly. Serve over noodles or rice.
