Note: If you don’t have fire-roasted tomatoes, you can use regular diced tomatoes. Any type of nut or seed butter will work, but only if it doesn’t have peanuts. Peanuts will have too strong a taste.
Notes: This can be made a day ahead of time or if you’re in a big hurry, press the sandwich down and bake right away.
Extra Romesco sauce and sandwich fillings will be used in Romesco Pasta with Olives, Sun-Dried Tomatoes and Artichoke Hearts recipe.
