If you slice them thinly enough, you can use fresh bell peppers here. Merguez is my spicy sausage of choice, but chorizo has a longer fridge life if that's a consideration.

This is a magnificent recipe - simple and delicious. If the peppers are marinated in garlic oil and oregano, it adds just a little more. Great stuff.
