In a large pot over medium heat, cook the lardons, chopped onions, and minced garlic for about 5 minutes or until the onion softens.
Cut the smoked sausages into bite-sized slices, about 1 cm (1/2 inch) wide.
With a fork or potato masher, mash approximately ½ cup of black beans to help thicken the stew. Add the smoked sausages, dried oregano, bay leaf, beef broth, and drained + mashed black beans to the pot. Stir to combine and let simmer, covered, for 15 minutes.
In a small bowl, mix 1 tsp cornstarch with a small amount of cold water. Stir to dissolve, and add to the hot stew. Simmer for 1 more minute to thicken.
Stir in black pepper to taste and a tablespoon of lime juice. Taste, and add salt if needed (I didn’t need to add any).
Serve over rice, with a slice of orange and sprinkled with plenty of chopped cilantro.
