My local grocery store carries piquillo peppers, they have them right next to the jars of regular roasted peppers. Trader Joe’s has them right now too, but I noticed that they’re imported from Peru rather than Spain, so I can’t vouch for the quality. You can also order them online. Unlike most jarred products, these peppers don’t have a very long shelf life. I usually end up freezing whatever I have left over after the jar has been open for a week.
You can use these peppers in any way that you would normally use your standard roasted red peppers. I like to put them in pasta, on pizza, or stuff them with a variety of fillings. One of my favorite preparations is to stuff the peppers with goat cheese, raisins and pine nuts. There’s no real recipe for this – I mix softened goat cheese with some toasted pine nuts, golden raisins that have been plumped in hot water, salt and pepper. If the mixture seems too thick, you can thin it slightly with a touch of milk or cream. I fill the peppers using a piping bag – you can use a spoon, but it’s a little messier. These are good at room temperature or just slightly warmed.

Makes 3-4 servings
1 tablespoon olive oil
1/2 medium onion, thinly sliced
8 piquillo peppers, thinly sliced

2 teaspoons lemon zest

Heat the olive oil in a pan at medium heat. Add the onion and cook until soft and browned, 5-7 minutes. Add the garlic and cook for one minute. Add the piquillo peppers, lemon zest, lemon juice and rosemary and cook for another 5-7 minutes. Add a little water if the pan gets too dry. Remove and discard the rosemary sprig. Stir in the vinegar and season to taste with salt and pepper.
