Step 1

Start by making your tzatziki sauce a few hours (or even days) ahead of time. Chop the cucumber and pat it dry with a few paper towels. Tzatziki should have a nice thick, creamy texture when done, so you want to drain any excess water from the cucumber. Drain off any standing liquid from the yogurt and add cucumber. Add remaining Tzatziki ingredients, stir well and refrigerate 2-3 hours until ready to use.

Step 2

While the tzatziki sauce chills, make your gyro meat patties. Combine all of the meat ingredients in a bowl and mix well. Form four rectangular patties, about 5-6 inches long and 1/2 inch thick. Grill or broil patties to your desired doneness.

Step 3

Finally, put it all together. Spread each pita round with a thin layer of tzatziki sauce, followed by a cooked gyro patty. Top patties with sliced onions, diced tomatoes and chopped dill, and finish with additional tzatziki sauce.
