The earthy flavor of roasted peppers is also great for sandwiches. Roasted red peppers make a great addition to a classic muffuletta. They are also delicious in a walnut romesco to top roast beef. Pimento cheese is a Southern classic that's very easy to make—mix cheddar cheese, aïoli, sriracha, cider vinegar, paprika, Worcestershire, and scallions with roasted red pepper and let it sit. This rich spread is perfect on a sandwich with cool iceberg lettuce and tangy homemade pickles.
