3 ounces thinly sliced pancetta, cut into 1/2-inch dice
6 ounces andouille sausage, sliced 1/2 inch thick
4 ounces smoked chorizo, halved lengthwise and sliced 1/4 inch thick
1 medium onion, cut into 1/2-inch dice
2 garlic cloves, minced
Two 15-ounce cans black beans, with their liquid
1 1/2 cups chicken stock or low-sodium broth
2 ounces Canadian bacon, cut into 1/2-inch dice
1 bay leaf
1 teaspoon red wine vinegar
Salt and freshly ground pepper
In a large saucepan, cook the pancetta over moderately high heat, stirring a few times, until it begins to brown around the edges, about 2 minutes. Stir in the andouille and chorizo and cook over moderate heat until the chorizo is browned, about 4 minutes.
Spoon off all but 2 1/2 tablespoons of the fat from the skillet. Stir in the onion and cook until tender, about 3 minutes. Stir in the garlic and cook until fragrant, about 1 minute. Add the black beans, chicken stock, Canadian bacon and bay leaf and stir well. Bring to a simmer and cook over low heat until the liquid has thickened, about 20 minutes. Stir in the red wine vinegar and season lightly with salt and pepper. Ladle the stew into bowls and serve.
