1 c. chili sauce
2 c. ketchup
1 1/4 c. Coca-Cola (Coke)
1 packet onion soup mix
1 (3 to 4 lb.) brisket (I also have used beef roast, trimmed)

Mix all ingredients together. Pour over brisket. Cover with foil.

Bake at 350°F for 3 to 4 hours. Note: If you do not want it very salty, just use a few tablespoons of the onion soup mix. Also you may not have to cook as long with a better cut of meat. Just reduce the amount of time.
