Prepare the Chicken: Clean the chicken and rinse in cold lemon water. Pat dry thoroughly with paper towels. Make slits across the chicken to allow seasoning to penetrate.
Season the Chicken: Season both sides of the chicken with salt, chicken bouillon powder, onion powder, garlic powder, and pepper. Massage the seasoning into the chicken evenly.
Prepare Wet Seasoning: Blend pebe, ginger, leek (or green onion), garlic, parsley, chicken bouillon powder, and avocado oil into a smooth paste.
Apply Wet Seasoning: Pour half of the spice blend over the chicken, massaging it into every nook and cranny. Place the chicken on a baking sheet lined with aluminum foil and an oven rack.
Bake: Bake at 450°F for 40 minutes.
Prepare Green Sauce: Add the remaining seasoning blend into a small pot. Rinse the blender with water and add to the pot. Bring to a simmer, adding a little more oil.
Serve: Serve the grilled chicken with the green sauce, optional fried plantains, and pepper sauce. Garnish with sliced onions and minced parsley.
