Step 1

In a large pot over medium, cook the bacon, stirring occasionally, until lightly browned and beginning to crisp, 4 to 6 minutes. Add the chopped onion; cook, stirring occasionally, until softened and beginning to brown, 4 to 5 minutes.

Step 2

Add the garlic, chipotle and adobo sauce, cumin and chili powder; cook, stirring, until fragrant, 1 to 2 minutes. Add the beans, broth and tomatoes. Bring to a simmer scraping up any browned bits, then reduce to medium-low and cook, stirring occasionally, until the mixture is slightly thickened, about 20 minutes.

Step 3

Off heat, taste and season with salt and pepper. Serve sprinkled with the finely chopped onion.
