Creating Pesto Caprese Grilled Cheese is a breeze when you follow these simple steps:

1. Prepare the Bread: Start by spreading a thin layer of butter on one side of each slice of bread.
2. Assemble the Sandwich: On the unbuttered side of two slices, spread a layer of pesto.
3. Add Cheese and Tomatoes: Layer the fresh mozzarella slices and tomato slices on top of the pesto. Sprinkle with salt and pepper for added flavor.
4. Add Basil: Place fresh basil leaves over the tomatoes and cheese.
5. Top the Sandwich: Place the other two slices of bread on top, with the buttered side facing out.
6. Heat the Skillet: Preheat a skillet over medium heat.
7. Cook the Sandwich: Once the skillet is hot, place the sandwiches in the skillet. Cook for about 3-4 minutes or until the bottom slice is golden brown.
8. Flip Carefully: Use a spatula to flip the sandwiches gently. Cook the other side for another 3-4 minutes, until golden brown and the cheese is melted.
9. Check for Doneness: Remove the sandwiches from the skillet when both sides are golden and the cheese is gooey.
10. Slice and Serve: Cut the sandwiches in half and serve immediately for maximum gooeyness.
