02 - 1/2 cup fresh basil leaves
03 - 1 small garlic clove
04 - 2 tablespoons grated Parmesan cheese
05 - 2 tablespoons toasted pine nuts
06 - 2 tablespoons extra-virgin olive oil
07 - 1/2 teaspoon lemon zest

12 - 2 tablespoons unsalted butter, softened
13 - 1 cup shredded mozzarella cheese
14 - 1/4 cup spring pea pesto
15 - Baby arugula or spinach leaves, optional
# Steps:
01 - In a food processor, combine peas, basil, garlic, Parmesan, pine nuts, olive oil, lemon zest, lemon juice, salt, and pepper. Pulse until mostly smooth but still textured. Taste and adjust seasoning as needed.
02 - Spread a thin layer of butter on one side of each bread slice. Place two slices buttered side down on a clean surface. Spread 2 tablespoons of spring pea pesto on each. Top evenly with mozzarella cheese and a handful of arugula or spinach if using. Cover with remaining bread slices, buttered side up.
03 - Heat a skillet or griddle over medium heat. Place sandwiches in the pan and cook for 3 to 4 minutes per side, pressing gently, until bread is golden and cheese is melted.
04 - Slice in half and serve warm immediately.
