Preheat oven to 170ºC.
Line a large baking tray with parchment paper – this saves on a lot of cleaning afterwards.
Chop the chicken into bite sizes pieces then add to the tray.
Peel the sweet potatoes and slices into thick chunks then chop the baby sweet peppers in half and deseed, then peel and chop the onions into quarters roughly and add to the tray.
Don’t peel the garlic, just remove the loose skin around each clove and add to the pan.
To make the sauce firstly separate the leaves from the coriander and leave them aside to decorate when the dish is cooked. Keep the stalks though and place them along with all the remaining sauce ingredients into a blender and blend until it becomes smooth and creamy.
Pour the sauce over the vegetables and chicken and using your hands make sure that everything is totally coated.
Scatter the baby tomatoes over the mix or if the tomatoes are still on the vine place on top then bake for 45 minutes. The vegetables should all be soft and squishy if you press them between your forefinger and thumb and the chicken should be lovely and moist.
Roughly chop the coriander leaves you set aside earlier and sprinkle over to serve.
