Instructions

  1. Step 1: Preheat a grill pan over medium heat. Brush 4 slices of artisan rustic bread lightly with 2 tbsp olive oil on both sides.
  2. Step 2: Spread 1 tbsp Romesco sauce evenly on two of the bread slices. Layer 6 oz sliced Manchego cheese and 1 cup sliced roasted red bell peppers on top of the sauce.
  3. Step 3: Top with the remaining bread slices to form sandwiches. Spread 1 tbsp butter on the outside of each sandwich.
  4. Step 4: Place sandwiches on the preheated grill pan and cook for 3-4 minutes per side until the bread is golden brown and the Manchego cheese melts.
  5. Step 5: Remove sandwiches from the pan, slice in half, and serve warm with extra Romesco sauce for dipping.
