1 540-mL can chickpeas, drained
2 tomatoes, chopped
1 cup chopped cucumber
1 cup diced cheese, (Swiss, cheddar, mozzarella, feta - whatever)
2 tbsp olive oil, or vegetable oil
1 tbsp vinegar, or lemon juice
salt, to taste
black pepper, to taste
2 or 3 6-in. pita breads, cut in half
In a bowl, combine all the above ingredients, tossing to mix everything evenly. Spoon into pita pockets and eat.
If your child wants to take this one to school, pack the filling in a separate container and have him stuff his own pita at lunchtime.
