Prepare the chicken: Slice the chicken breasts horizontally and season with salt, pepper, paprika, and oregano.
Sear lightly: Quickly sear the chicken in olive oil for 1–2 minutes each side (just for color).
Add feta mixture: Place chicken in a baking dish, add crumbled feta, cherry tomatoes, garlic, olive oil, and chili flakes.
Bake: Bake at 200°C for 15–18 minutes until the feta melts and the chicken becomes juicy.
Crisp under broiler: Broil for 1–2 minutes to get the feta golden and crispy.
Serve: Garnish with basil and serve with rice, pasta, or roasted potatoes.
