Preheat oven to gas mark 6.
Add chickpeas to a bowl and toss with oil, cumin, coriander and smoked paprika powders.
Add garlic cloves and chickpeas to an oven tray.
Drizzle the garlic with a bit of olive oil. (Now prepare the sweet potatoes so they can go into the oven at the same time following the instructions for sweet potato below).
Bake for 20 minutes, or until the chickpeas are golden brown and very slightly crispy. Add the salt and pepper whilst still hot.
The garlic should be fragrant and slightly browned. Remove from oven and set aside.
Squeeze garlic out of skins once cool and mash as much as possible.
Add it to the chickpeas. Toss through with your hands.
