Coca Cola Sloppy Joes

1 1/2 pounds lean ground beef
1 large onion, chopped
1 cup Coca-Cola
1 cup thick, tomato-based barbecue sauce
6 hamburger buns

In a nonstick skillet over medium-high heat, brown the beef with the onion until onion is soft and meat is no longer pink, about 5-10 minutes. Reduce heat to medium; stir in cola and barbecue sauce and continue to cook, stirring occasionally, until sauce is thickened to desired consistency, another 10-15 minutes. Season to taste with salt and pepper.

Toast cut side of buns, if desired, under broiler or in a skillet. Heap mixture onto buns. Serve.
Makes 6 servings.
