Step 1

Wrap meat tightly in plastic wrap, and place in freezer 15 minutes. Remove from freezer, unwrap meat, and slice thinly against the grain. Stack slices; finely chop. Place the meat in a bowl, and season with Worcestershire, 1 1/2 teaspoons salt, soy sauce, and black pepper. Stir until well coated, and set aside.

Step 2

Heat oil in a medium Dutch oven over medium. Once the oil is shimmering, add garlic, and cook until fragrant, about 1 minute. Add seasoned meat, and cook until it releases some of its juices, about 10 minutes. (It’s OK to crowd the pan—you want to encourage the meat to stew and release its juices.) Reduce heat to low to keep the liquid from reducing too much. Using a slotted spoon, remove and reserve 2 tablespoons cooked meat.

Step 3

While the meat cooks, place tomatillos in a saucepan with just enough water to cover, about 3 1/2 cups. Cover with a lid, and bring to a boil. Cook until tomatillos are soft, about 5 minutes. Remove from heat; drain.

Step 4

Place quartered onion half, cooked tomatillos, and reserved 2 tablespoons meat in a blender with 1 cup broth; blend until smooth, about 1 minute. Add mixture to meat in pot; add remaining 3 cups broth and bay leaves. Season with remaining 2 teaspoons salt. Bring to a boil, and reduce heat to medium-low; simmer about 20 minutes. Add cooked beans, and cook until the meat is tender, about 10 minutes.

Step 5

Using a slotted spoon, place about 1 cup or more of the meat-and-bean mixture into each bowl. Add broth as desired, and garnish with chopped onion, cilantro, Key lime wedges, and bacon. Serve with toasted tortillas.
