Combine cola and next 7 ingredients; Cover and chill one cup of sauce. Pour remaining sauce over roast. Cover and cook at high 6 hours or at high 1 hour and at low 7 to 8 hours until roast is very tender.
Remove roast and chopped onion from cooker with slotted spoon. Shred meat with two forks. Reserve remaining meat juices to spoon over mashed potatoes or toast, if desired.

Wipe roast with damp paper towel. Sprinkle with unseasoned meat tenderizer and set aside. Combine marinade ingredients together and mix thoroughly.
Easy and delicious beef recipe. Good to use with less expensive or tougher meat.
This is a hearty meal. It is easy to prepare and when winter gets here, this would be a meal to warm you up.
This is a great way to stretch a roast! I like to serve this over rice, but it's also good by itself.
Place meat in a roasting pan, mix and add all ingredients and pour over the top. Cover and bake at 350 degrees F for about 2 hours or until tested done. Serves 6-8.
Brown roast in pan on both sides, until brown. While it's browning, boil 1 coffee pot full of water (in coffee pot). When roast is brown, leave in same pan you browned it in, pour hot water over it.
