Step 1

In the slow cooker, stir together the beef, tomatoes, onion, bell pepper, Worcestershire sauce, chili powder, garlic, cinnamon, salt, and pepper. Cook, covered, on low for 8 to 9 hours or on high for 5 to 5 1/2 hours, or until the beef is tender.

Step 2

About 10 minutes before serving time, prepare the couscous using the package directions, omitting the salt and substituting the broth for the water. Spoon into bowls. Ladle the stew onto the couscous. Top with the mango and cilantro.
