1/2 tsp. salt

1/2 tsp. pepper

2 medium onions, cut into thin wedges

4 cups root beer, divided

6 cloves garlic, minced

Several dashes bottled hot pepper sauce (optional)

1 cup bottled chili sauce

hamburger buns, split (and toasted, if desired)

Lettuce leaves (optional)

Trim fat from meat.

If necessary, cut roast to fit into a 31/2- to 5-quart crockpot.

Sprinkle meat with salt and pepper.

In a large skillet, brown meat on all sides in hot oil.

Drain off fat.

Transfer meat to crockpot.

Add onions, 1 cup of root beer, and garlic.

Cover and cook on low-heat setting for 8 to 10 hours or on high-heat setting for 4 to 5 hours.

Meanwhile, for sauce, in a medium saucepan combine the remaining 3 cups of root beer with the chili sauce.

Bring to boiling; reduce heat.

Boil gently, uncovered, stirring occasionally, about 30 minutes or until mixture is reduced to 2 cups.

Add bottled hot pepper sauce, if desired
