Creating the Turkey Pesto Sandwich is simple and straightforward. Just follow these easy steps:

1. Prep the Bread: Start by laying out your slices of bread on a clean surface.
2. Spread Pesto: Take about a tablespoon of pesto and spread it evenly onto one side of each slice of bread.
3. Layer Turkey: Place 4-6 slices of turkey breast on top of the pesto on one slice.
4. Add Cheese: If using, add one slice of mozzarella cheese over the turkey.
5. Top with Vegetables: Add fresh arugula and tomato slices on top of the cheese.
6. Season: Sprinkle a pinch of salt and pepper for added flavor.
7. Grill or Toast (Optional): If you prefer a warm sandwich, heat a skillet over medium heat. Drizzle a bit of olive oil and place the sandwich in the skillet. Grill for about 2-3 minutes on each side until the bread is golden brown and the cheese is melted.
8. Serve: Remove from the heat and slice the sandwich in half for easier handling.

This quick assembly process makes it snap to prepare, and you'll be delighted by the flavor.
