Cook chicken: Preheat large skillet on medium-high heat and swirl oil to coat. Add chicken, sprinkle with salt and pepper, and cook for 8-10 minutes or until tender, stirring a few times.
Sprinkle with oregano, thyme and red pepper flakes. Cook for another 1-2 minutes, stirring a few times. Transfer to a large plate and set aside.
Cook zucchini: Return skillet to the stove and swirl oil to coat. Add zucchini and bell peppers, sprinkle with salt, pepper, oregano, thyme and red pepper flakes. Cook for 5 minutes, stirring a few times.
Finish the skillet: Return previously cooked chicken to the skillet along with tomato, garlic and parsley, then stir to combine.
Turn off heat and add evenly the olives, red onion and feta cheese on top. You can also squeeze the lemon juice.
Serve hot or cold with rice, pita, tzatziki or on its own with tzatziki for a low carb-high protein meal.
Notes
Store: Refrigerate covered for up to 3 - 4 days. Do not freeze.
To reheat: Simmer on low heat in a skillet for 5 minutes covered. If you use non-stick skillet you should not need any water or oil to reheat the dish as again zucchini will release water.
Do not over cook zucchini: Follow the recipe and do not cook until zucchini appear soft and cooked.
