Preheat oven to 200oC fan forced. Peel and cut the sweet potatoes into large cubes. Place the sweet potatoes and sliced onions on a lined baking tray.
Drizzle with approx. 1-2 tablespoons of oil (20-40 ml).
Bake for 15 minutes, then toss the sweet potatoes & onions well & cook for a further 10 minutes. Add the sliced broccolini & drizzle with a bit of oil and season with a pinch each salt and pepper. Toss well so it takes in some of the lovely pan flavours. Note - if the broccolini has large stems, these can be sliced or chopped into smaller pieces so they cook evenly within the cooking time.
Bake for 8-10 minutes, then remove from oven and add kale. Drizzle kale with a touch more oil and season with a pinch each salt and pepper. Bake for another 4-5 minutes. Remove tray from oven.
Meanwhile, pat dry the chickpeas with some paper towel.
Place chickpeas in a pan & add the extra virgin olive oil and all the spices & seasoning. Mix to combine well.
Cook over a low-medium heat for 8-10 minutes, stirring often. If they are popping out of the pan, your heat needs to come down. 10 minutes over low-medium heat is pretty accurate. Remove from heat and set aside.
To make the tahini yoghurt dressing, mix the yoghurt with tahini and lemon juice and season with salt, to taste. Add just a little hot water until a pourable sauce is formed. Set aside.
To serve, divide the vegetables between 3 serving bowls and top with chickpeas + tahini sauce.
Best enjoyed straight away although leftovers will keep for a few days in the fridge and can be added to other meals throughout the week.
