This is my yogurt recipe:
6 oz plain Greek yogurt
1 cup seeded, shredded (or finely chopped) cucumber
1/4 cup crumbled feta
1 teaspoon dried dill
1 tablespoon olive oil
1/2 tsp garlic powder
1/4 teaspoon salt
For the cucumber, I take the skin off with a vegetable peeler, and then continue to use the peeler to shred the entire cucumer into thin slices, and then I take a large knife and chop up the thin strips into tiny pieces -- it takes maybe a couple of minutes if that.
For the chicken, I cut up chicken breasts and marinade in olive oil, lemon juice, salt, pepper, and oregano (and if I am ambitious, minced garlic and onion) for a few hours or overnight and then I just saute them and serve with pitas, fresh chopped tomatoes, and the yogurt sauce.
