Ingredients

For the Walnut Pesto:

  • ½ cup walnuts toasted
  • 1 cup fresh basil leaves
  • 2 garlic cloves
  • ¼ cup grated Parmesan cheese
  • 1 tablespoon lemon juice
  • Salt and pepper to taste
  • ¼ cup olive oil

For the Sandwich:

  • 2 chicken breasts about 6 oz each, seasoned with salt and pepper
  • 1 tablespoon butter or olive oil, for toasting the bread
  • 1 medium sourdough baguette halved lengthwise
  • 1 cup fresh mozzarella sliced
  • 1 medium tomato sliced
  • A handful of arugula

Instructions

  • In a food processor, combine toasted walnuts, 1 cup basil leaves, 2 garlic cloves, ¼ cup Parmesan cheese, 1 tbsp lemon juice, salt, and pepper. Pulse until finely chopped.
  • Combine shredded chicken with the prepared pesto.
  • Heat a skillet over medium heat with 1 tbsp butter (or olive oil). Slice a medium sourdough baguette in half and toast in the pan until golden and crisp, about 2-3 minutes per side.
  • Fill the toasted baguette halves with the pesto-chicken mixture, 1 cup sliced fresh mozzarella, 1 sliced tomato, and a handful of arugula.
  • Slice the assembled sandwich in quarters and serve right away.

Notes

Make the pesto ahead of time and store it in the fridge for up to 3 days.
Shred the chicken while it’s still warm—it’s much easier.
Use a panini press if you want an even crispier, melty version.
