Diced scallions, jalapenos, or parsley, for garnishment
Place the olive oil in the bottom of a large pot or Dutch oven and add the ground beef. Brown the beef over medium heat until no longer pink, drain any excess fat.
Transfer beef back to pot; stir in the onion, peppers, and garlic. Simmer over medium heat until the onions are translucent, about 8 minutes. Stir in the flour and continue to simmer an additional minute stirring continuously. Add the chili powder, cumin, paprika, beans, tomato sauce, beef broth, and dark beer. Mix together.
Stir in the pasta and bring back to a simmer. Reduce heat to low and continue to simmer for 15 minutes; stirring frequently to avoid sticking to the bottom of the pot.
Remove from heat and stir in the cheese. Spoon into individual serving bowls and garnish with desired garnish. Serve immediately.
