Preheat the oven to 200°C (400°F).
Season the chicken leg with a teaspoon of Onje mix seasoning and a small amount of olive oil, then sprinkle some salt.
Place the seasoned chicken in an oven dish and bake for about 30 minutes until golden brown.
In a separate pan, heat 2 tablespoons of olive oil and sauté the sliced carrot, crushed garlic, and seasoned vegetables (1 tablespoon Onje mix seasoning) until tender.
Add 3-4 chicken stock cubes with 1 cup of water to the veges and stir well. Place the oven dish containing the chicken in this liquid for further cooking.
Meanwhile, prepare a spicy butter sauce by melting 3-4 tablespoons of butter in a pan. Add sliced red chili peppers, lemon juice, honey, salt, and a bit of chopped parsley.
After about an hour of baking the chicken with vegetables, remove it from the oven and add the broccoli florets to the dish. Continue cooking for another 10 minutes, ensuring that the chicken is flipped 2-3 times during this time.
Serve the roasted chicken and vegetables hot, drizzled with the spicy butter sauce.
