Preheat the oven to 200°C, and chop all the veggies. Put your potatoes in water to avoid them browning (take them out and dry them immediately before using).
Mix all the marinade ingredients together.
In an ovenproof dish place your chicken in the center and pat it dry. Add the squeezed lemon halves in the cavity of the chicken, and if you like you can tie the legs together (breast side up).
Add the veggies all around and using gloved hands mix the marinade into the chicken and veggies. Make sure to get into every corner.
Bake for about an hour at 200°C , uncovered at first and then cover when your chicken begins to brown. I was late in covering mine! You do not need to add any water in the pan as the veggies will ooze water and it will be enough for everything to cook nicely. Sahtein!
