Heat a skillet over medium-high heat. Add some olive oil and the chorizo, and cook, breaking the meat up with a spoon, until browned, about 5 minutes. Add the bell pepper, onion, chili powder and tomatoes and cook until slightly thickened, about 5 minutes.
Preheat the broiler. Transfer the chorizo mixture to an oven-safe dish and layer on the Muenster, manchego and Gruyere.
Broil until the cheese is melted and golden brown. Serve with the baguette slices.
