1 (3 pound) beef boneless eye of round
roast or rolled rump roast
1/2 pound bulk chorizo
2 tablespoons olive oil or vegetable oil

3 cloves garlic, finely chopped

Cut a narrow (1-inch) X shape all the way through the center of the beef roast with long, thin sharp knife. Fill X cuts with sausage. Heat oil in Dutch oven until hot. Cook beef over medium heat until brown on all sides, about 15 minutes; drain fat.
Add remaining ingredients. Heat to boiling; reduce heat. Cover and simmer until beef is tender, 2 to 2 1/2 hours.
Remove bay leaves. Slice beef; arrange on platter. Skim fat from sauce. Pour some of the sauce over beef.
Serve beef with remaining sauce and hot cooked black beans or rice, if desired.
