Clean and oil cooking grate. Place patties on hotter side of grill, cover (if using gas), and cook until well browned and crust forms, 4 to 6 minutes per side. Transfer patties to paper towel-lined plate, cover loosely with foil, and let sit while heating pitas.
Place packet of pitas on cooler side of grill and flip occasionally until heated through, about 5 minutes. Using spoon, spread 1/4 cup Tzatziki inside each warm pita. Divide patties evenly among pitas and fill each sandwich with tomato slices, 1/2 cup shredded lettuce, and 2 tablespoons feta. Serve immediately.
Tzatziki is a traditional Greek sauce made from strained yogurt and cucumber, as delicious eaten as a dip for raw vegetables as it is dolloped over grilled chicken or lamb. To make our own classic version, we started by shredding a cucumber on a coarse grater, salting it, and letting it drain to keep any excess liquid from watering down the dip. Greek yogurt gives Tzatziki its pleasant tang and richness, but before stirring in our drained cucumber, we enhanced its flavor with minced fresh herbs and garlic. Using Greek yogurt here is key; do not substitute regular plain yogurt or the sauce will be very watery.
