Souvlaki Gyro 

Ingredients:

4 pita bread rounds
Tzatziki
1 serving previously prepared souvlaki
1 large onion, chopped
2 medium tomatoes, diced
Crumbled feta cheese
Dried oregano, to garnish

Place a piece of aluminum foil down on a flat surface. 
Put a piece of bread in the center of the foil. 
Spread a generous amount tzatziki across the middle of the pita bread. 
Top with chopped onion and tomato and then add the souvlaki meat. 
Sprinkle with feta cheese and drop another spoonful of tzatziki over the top, if desired.

Roll the gyro sandwich and wrap it in aluminum foil so it can hold the shape. 
Repeat until you've used up all the bread.
