Taste of Home's Pull Beef Sandwiches

This recipe is rated very high on Taste of Home's website. It's a great meal for Sunday when you want to just throw something in the crock pot. I used hamburger buns instead of Kaiser rolls. (It's what I had in the freezer :)

Ingredients:

3/4 cup cola
1/4 cup Worcestershire sauce
2 garlic cloves, minced
1 tablespoon white vinegar
1 teaspoon reduced-sodium beef bouillon granules
1/2 teaspoon chili powder
1/2 teaspoon ground mustard
1/4 teaspoon cayenne pepper
1 beef rump roast or bottom round roast (2 pounds)
2 teaspoons canola oil
2 medium onion, chopped
1/2 cup ketchup
8 kaiser rolls

Preparations:

1. In a 4-cup measuring cup, combine the cola, Worcestershire sauce, garlic, vinegar, bouillon and seasonings; set aside. Cut roast in half. In a nonstick skillet, brown meat in oil on all sides.
2. Place onions in a 3-qt. slow cooker. Top with meat. Pour half of cola mixture over meat. Cover and cook on low for 8-10 hours or until meat is tender. Cover and refrigerate remaining cola mixture.
3. Remove meat from cooking liquid and cool. Strain cooking liquid, reserving onions and discarding the liquid. When meet is cool enough to handle, shred with two forks. Return meat and onions to slow cooker. 
4. In a small saucepan, combine ketchup and reserved cola mixture; heat through. Pour over meat mixture and heat through. Serve on rolls. Yield: 8 servings.
