Combine all the ingredients--except barbecue sauce--in a bowl, stir and pour over brisket. I like to marinate the brisket right in the slow cooker insert. Marinating is optional but it really adds to the flavor. Marinate brisket in the refrigerator overnight if preferred, otherwise move to the next step.
All marinate ingredients go in the slow cooker, stir and add brisket. Cover and cook on low 8 hours or until tender and easily flakes with a fork.
Preheat oven to 350 degrees. Add brisket, along with 1/2 cup juices from the slow cooker, to a roasting pan. Discard the remaining liquid along with bay leaves. Either pull the brisket apart with 2 forks or slice thinly across the grain. Pour barbecue sauce over brisket and heat for 15 minutes. Serve on toasted wheat buns or rolls if desired.
If your brisket has a layer of fat, be sure to place the brisket fat side up in the slow cooker. After brisket is done and goes in the roaster pan, remove fat and discard before shredding, slicing or adding barbecue sauce.TIP: To lower the calories, fat and carbohydrates, simply cut the serving size in half...which will equal 1/2 cup.
