Set aside.Wash the sweet pointed pepper, remove the seeds and core, cut in half, then quarters, and dice. Set aside. Cook the pasta in salted water until al dente. It takes 10-14 minutes, so it’s good to start it before cooking the meat. Reserve about half a cup of the cooking water.
Drizzle a little olive oil into a deep frying pan, add the onion, sauté until translucent, then add the zucchini and sweet pointed pepper. Sprinkle with Italian seasoned salt and oregano. Sauté all the vegetables while stirring, then pour them into a bowl and set aside while you cook the meat.
In a hot pan, fry the marinated chicken until golden brown. Return the cooked vegetables to the pan, stir together and let them lightly sauté together. Pour in some of the reserved pasta cooking water, then add the drained pasta. Stir well and cook until creamy.
Finally (still in the pan), stir in the diced feta cheese. There’s no need to cook further.
When serving, put one tablespoon of plain Greek yogurt on each portion.
