Cook bacon in a frying pan. Remove from heat and reserve. In the same pan, sear beef with bacon fat until the meat has lost its red color. Season with salt and pepper to taste. Blend tomatoes, chiles, onions, cilantro and garlic and pour into a pot. Add the meat and its juices with bouillon cubes. Cover and cook over medium-high heat until the pressure rises. Reduce heat to low and simmer for 20 minutes. Add beans to the pot. After 10 minutes, add the bacon. Serve in a bowl and add finely chopped onion and cilantro. Serve with corn tortillas.

Serves 4.
