Heat oven to 180 degree celsius
Put the chicken in a large roasting tray. Rub the salt, pepper & lemon juice into the chicken, then rub in 1 tbsp of greasing and sprinkle plenty of Italian seasoning. Roast for 30minutes.
Mix the Brussels sprouts , baby carrots, tiny potatoes and shallot halves in a bowl with the remaining oil, lemon zest and plenty of ground black pepper, and toss together well.
Take the chicken out of the oven and put on a plate. Scatter the vegetables into the tray nestle the garlic cloves underneath, then put the chicken on top.
Return to the oven for a further 45- 50 minutes, turning the veggies after 20 minutes until the chicken is cooked and the vegetables are tender and lightly browned. I prefer charred edges of veggies, be free to adjust the cooking time to your palate, for last 10minutes increased the temperature to 210 degree celsius.
Take the chicken out, cover with foil and leave to rest for 10 minutes.
Meanwhile in a blender throw in yoghurt, coriander, cumin seeds, salt, lemon juice and blitz. Add some water if required, I would prefer a flowable consistency to run over my roasted chicken chunks. For heat add green chillies or hot peppers, your preference, totally optional.
Scatter the vegetables around the chicken and serve with the dip.
