Its actually really simple to make this roasted chicken. All you have to do is marinate the meat in some teriyaki sauce, oyster sauce, a little mixture of chili-tomato sauce and some honey. I can't give a specific measurement but all I can say is, taste the mixture and if the flavors are balanced and tastes right for you then its done! If possible, let your chicken marinate for an hour or longer before you roast it. Set your oven to 190ºC / 375ºF and roast your chicken for 40 minutes or more (depending on the size of the chicken).
Roasting chicken can get your oven messy, so here's a tip. Line the oven's baking tray with foil paper and place it in the lowest part of the oven. The chicken parts should be on the oven's wire rack shelf placed in the center of the oven. While roasting the chicken, the juices/fats will fall onto the foil paper instead of the tray, making it easier to clean up after.
Back at home, when my mum makes roasted chicken, she usually serves it with some french fries and coleslaw. I decided to make a healthier version by making some roasted pumpkin instead. Its easier to make as well. Just slice the pumpkin into wedges, coat the sliced pumpkin wedges with some olive oil, sprinkle some black pepper on it and pop them into the oven at 180ºC / 356ºF for 20-30 minutes (depending on the size of the wedges). Simple isn't it?
Try it for yourself!
