Step 1

To a large skillet, add the oil, chicken, evenly sprinkle with oregano, salt, pepper, and cook over medium-high heat for about 5 minutes, flipping intermittently so all sides cook evenly.

Step 2

When chicken is about 90% cooked through, reduce the heat to medium-low, add the red wine vinegar, lemon juice (use caution because it will bubble up), and allow chicken to simmer another 1 to 2 minutes, or until done. Cooking time will vary based on thickness of chicken breasts and sizes of pieces.

Step 3

Set pan aside off the heat while you assemble the salad.

Step 4

To a medium bowl, add all ingredients, whisk to combine, taste, and check for flavor balance. Add additional salt, pepper, lemon juice, pinch sugar, etc. if necessary, to taste.

Step 5

Lightly toast each piece of pita bread. You have a few options for this: toast over a low flame on a gas stove, grill briefly on an outdoor gas grill or indoor grill pan, bake for about 10 minutes in a 450F oven (or until lightly crisp), or simply add to your toaster.

Step 6

To each pita bread, add a light coating of tzatziki sauce or to taste, and evenly top with all remaining ingredients, to taste. Pizzas are best fresh.
