In a medium skillet, cook sausage over high heat, breaking it up as it cooks.
Combine sausage, peppers, onion, garlic, tomatoes, tomato sauce, tomato pasted, salt, pepper, crushed red pepper and water in a slow cooker. Give it a good stir.
Cook on high for 4 hours or low for 8 hours.
To serve as a sandwich, use a slotted spoon to spoon out peppers and onions (shaking of excess sauce) and place in a hoagie roll. Top with provolone or mozzarella cheese. Melt under the broiler on low until Cheese has melted and bun is crispy.
