Instructions

  1. Step 1: Spread 1/4 cup romesco sauce evenly on two slices of 4 rustic bread slices. Layer each with 3 oz sliced Manchego cheese and 1/4 cup roasted piquillo peppers.
  2. Step 2: Top with remaining bread slices to form sandwiches. Spread 1 tbsp butter on the outside of each sandwich.
  3. Step 3: Heat a nonstick skillet over medium heat. Place sandwiches butter-side down and grill for 3-4 minutes until golden and crispy. Flip carefully and grill the other side with remaining 1 tbsp butter for another 3-4 minutes until cheese melts and bread is toasted.
  4. Step 4: Remove sandwiches from skillet, let rest 2 minutes, then slice in half and serve warm.

How do I store leftover Grilled Manchego and Piquillo Pepper Sandwich with Romesco Sauce?

Transfer to an airtight jar and refrigerate for up to 5–7 days. Most sauces freeze well for up to 2 months — portion into small containers or freezer bags so you can thaw only what you need. Stir before serving; cream- or yogurt-based sauces may separate on standing.

Can I substitute ingredients in Grilled Manchego and Piquillo Pepper Sandwich with Romesco Sauce?

For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Grilled Manchego and Piquillo Pepper Sandwich with Romesco Sauce for a different number of people?

The recipe is written for 2 servings. Multiply each ingredient by (your serving target / 2). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
