Form into 4 large, very thin patties. Wash up and preheat a large nonstick skillet with a couple tablespoons extra-virgin olive oil over medium-high heat. Cook patties 3 to 4 minutes on each side. Heat a small second skillet over high heat and blister the pitas on each side. Cut tops off the bread and fill pita pockets with patties, lettuce and chutney.
