This comfort-food sandwich is great for breakfast, lunch, or dinner. It’s made with a lot of pantry staples, perfect anytime you need a quick meal. You can really use whatever combination of vegetables you like or have on hand: bell peppers in any color, zucchini, or squash, or add some heat by using jalapeños or serranos in place of the Cubanelle. The Cubanelle, also known as the Cuban pepper or Italian frying pepper, has a mild, sweet flavor and thin walls, which makes it ideal for quick cooking. You’ll find these imperfectly shaped peppers in a range of colors, from yellow-green to orange to red.
