Peel onions. Cut an incision into the centre of the onion. This is will allow you to peel the skin off later.
Bring a pot of water to a boil and add in the onions. Turn to a low heat and cook for 15- 20 minutes. Drain and allow to cool.
Preheat oven to 180C/350F.
Mix the filling ingredients together.
Carefully separate each layer of onion.
Add one tablespoon of filling into an onion peel and tightly roll.
Place in a oven-safe pan or oven tray. Repeat until ingredients are used up and place the whole garlic bulb in the middle.
Whisk together the sauce ingredients and pour over.
Bake in the oven for 45 minutes with a lid or covered in foil. Then remove the lid/foil and bake for another 30 minutes until golden and crispy.
Serve on a bed of thick plant-based yoghurt.
