In a medium skillet over medium-high heat, add the oil. When it is hot, add the sausage pieces and cook until lightly browned, about 5 minutes. Turn the heat to medium and add the reserved tomatoes, reserved beans and chicken broth. Cook until everything is hot and bubbling, 3 to 5 minutes.
Meanwhile, in a small skillet over medium heat, melt the butter. Add the breadcrumbs and cook, stirring frequently, until they are browned, about 5 minutes.
To serve, divide the sausage and beans into 2 bowls and spoon the breadcrumbs on top.
Beans and Bacon Macaroni:
Cook the bacon in a large skillet, working in batches, until it is crisp. Drain on a plate lined with a brown paper bag or paper towels. Chop into 1/2-inch pieces.
Remove all except 1 tablespoon of the bacon fat from the skillet and put it over medium heat. Add the onions and cook until they are soft, about 5 minutes. Add the garlic and cook for about 1 minute, being careful not to let the garlic burn. Add the tomatoes and beans and cook until the beans are heated through, about 2 minutes. Stir in the bacon and parsley. Reserve 1 1/2 cups for the Round 2 Recipe French Bean Stew.
