Combine chicken and 3 tablespoons pesto. Form into 3 burger patties. Pat firmly so your burgers don’t fall apart in the pan.
Sprinkle a fine layer of fine salt (about 1/2 teaspoon) on your frying pan or BBQ hot plate and get it nice and hot. Pop burger patties on the salt and cook for 4-5 minutes on the first side until well browned. It’s important to cook the burgers for long enough to form a good crust to form so they don’t fall apart when you turn them over.
Turn carefully and cook for 3-5 minutes on the second side or until burgers are cooked through.
Spread extra pesto on the base of each burger bun. Top each with a cooked patty, salad leaves, mayo and the top of the bun.
