Marinate the Chicken: Season chicken thighs with salt, pepper, garlic powder, thyme, and oregano. Drizzle with olive oil, mix well, and let it sit while you prep the potatoes.
Preheat an air fryer to 400°F (204°C). (Or use oven.)
Parboil Potatoes: Boil the potato chunks in salted water until just tender, about 5 - 7 minutes. Drain well.
Dressing: Mix lemon zest, lemon juice, olive oil, oregano, red pepper flakes, salt, and honey.
Cook Potatoes:
Air Frying: Toss potatoes with half the dressing. Place in the air fryer basket in a single layer. Cook for 15 minutes, shake, drizzle more dressing, and cook for another 10 minutes until crispy.
Oven Roasting: Toss potatoes with half the dressing and spread on a baking sheet. Roast for 20 minutes, stir, add more dressing, and finish roasting until golden and crisp, about 20 more minutes.
Cook the marinated chicken in a skillet over medium-high heat until browned to an internal temperature of 160°F (71°C).
Arrange the chicken and crispy potatoes on plates. Drizzle with the remaining dressing and sprinkle with feta cheese.
Make the Salad: Mix all ingredients for the dressing. Set aside. Mix all ingredients for the salad. Place into serving bowls, and toss with the dressing.
Mix lemon juice, water, and sugar to taste. Serve over ice if desired.
