Preheat your grill to medium heat.
Place the chicken, breast-side down, on a cutting board. Cut along both sides of the backbone from end to end with kitchen shears and remove the backbone. Flip the chicken breast side up, and open it like a book. Press firmly on the breasts with your palm to flatten (you should hear the breastbone break).
1 whole chicken
In a bowl, combine the olive oil, paprika, dried oregano, garlic powder, onion powder, lemon zest, and lemon juice, and season with salt and pepper to taste.
2 tsp. paprika, 1 tsp. dried oregano, 1 tsp. garlic powder, 1 tsp. onion powder, zest and juice of 1 lemon, 4 tbsp. olive oil, Sea salt and freshly ground black pepper
Brush the chicken with the paprika sauce.
Place the chicken on the grill, skin-side down, and grill for 8 to 10 minutes.
Turn the chicken over, close the cover, and continue cooking for another 8 to 10 minutes or until cooked through.
Serve with BBQ sauce, if desired.
