Preheat the oven to 350F.
In a large baking sheet add the chicken, potatoes, peppers, red onions, lemon wedges, garlic, and tomatoes.
Sprinkle with oregano, paprika, salt and pepper and drizzle with olive oil. Gently toss until well coated.
Bake in the preheated oven for 40-45 minutes, or until chicken is cooked through and veggies are tender.
Remove from the oven and stir in crumbled feta cheese and olives. Garnish with fresh thyme and enjoy it!
