Braseltouille - Meatatarian Ratatouille

Preheat the oven to 350 degrees F (175 degrees C).

Cook and stir sausage in a large skillet over medium heat until sausage is crumbly and no longer pink, about 10 minutes. Transfer sausage to a large bowl using a slotted spoon; set aside. Reserve 1 tablespoon drippings in skillet; drain excess grease. Cook and stir bell pepper, onion, and garlic in drippings until bell pepper is soft, about 8 minutes; transfer to the bowl with sausage.

Add olive oil to the hot skillet; cook and stir yellow squash and zucchini until slightly softened, about 8 minutes. Stir in tomatoes and Italian seasoning; season with salt and black pepper. Bring to a boil; simmer until squash are tender, 10 to 15 minutes.
