Place garlic, onions, beef broth, diced tomatoes and all seasonings on top (besides salt and pepper). As for the chipotle peppers - add 3 large whole peppers and 2 scant tablespoons of adobo sauce into crock pot. ***I think this adds the perfect amount of smokey flavor and heat. If you're concerned about it being too much - I'd reduce the sauce to a tablespoon and only add 2 peppers***
