Step 1

Add the ground beef to a skillet over medium-high heat and cook until browned, about 5-7 minutes. Add the seasonings and 1/2 cup of water. Simmer over medium heat until the sauce has thickened around the meat, about 5 minutes.

Step 2

While the beef cooks, make the Tzatziki sauce. Start by squeezing the excessive liquid out of the grated cucumber, discarding the liquid. In a small bowl, mix the grated cucumber with the remaining ingredients.

Step 3

To assemble a gyro, layer a pita with lettuce, tomato, cucumber, onion, and ground beef, then finish with tzatziki sauce, fresh dill and feta cheese.
