This recipe uses a food processor to make a pesto that is served with the pork belly crostini. The pork belly is first seared in a pan and then cooked in the oven until tender. The pesto is made by combining basil, garlic, pine nuts, and parmesan cheese in the food processor and pulsing until smooth. Serve the pork belly on toasted baguette slices with the pesto, sliced cherry tomatoes, and a sprinkle of sea salt for a delicious and easy appetizer.
