Preheat the oven to 205°C (400°F) for 10 minutes.
Line the baking tray with aluminum foil or if you don't want to use aluminum foil you can lightly oil the baking tray or dish.
In a mixing bowl add in the butter, oil, red chilli powder, mixed herb, peri peri spice mix, black pepper powder, salt to taste and ginger garlic paste. Combine all the ingredients well.
Take the clean chicken and pat dry with clean kitchen towel.
Using a knife or fork prick the chicken nicely from the inside of the skin. These will allow the spice to penetrate well inside the chicken while roasting and result in a well spiced and flavorful chicken.
Rub the spice mixture in the inside and outside of the chicken. Apply the mixture well all over the chicken. (You can also keep it marinated for few hours or overnight, I kept for few minutes while I did the other preparation)
Place the chicken onto the prepared baking tray.
Place the veggies around the chicken randomly. Take the leftover spice mixture and apply them on the veggies.
Pop in the chicken in a preheated oven and roast the chicken leg quarters uncovered at 205-210° C for 35 to 40 minutes. You can turn over the chicken in mid way. This step is optional but I like doing that.
Remove from oven and transfer to a serving dish. If there is any leftover sauce from the tray, rub or pour them over the roasted chicken. Enjoy!
