3 pounds beef boneless chuck roast (try to get the leanest meat available)
1 cup barbecue sauce
1/2 cup apricot preserves
2 tablespoons red or green bell pepper — chopped
1 tablespoon Dijon mustard
2 teaspoons brown sugar — packed
1 small onion — sliced
12 whole grain hamburger buns or Kaiser rolls — split
Remove excess fat from beef. Cut beef into 4 pieces. Place beef in 4 or 5 quart slow cooker.
Mix remaining ingredients except buns; pour over beef. Cover and cook on low heat setting 7 to 8 hours or until beef is tender. Remove beef from slow cooker. Cut beef into thin slices; stir back into sauce. Cover and cook on low heat setting 20 to 30 minutes longer or until beef is hot. Fill buns with beef mixture. Spread the buns with horseradish sauce for a delicious flavor kick!
