Pierce the sweet potato with a fork and add to the microwave and cook for 5 mins (test for softness, if still a little hard, add for another minute or so, allow to cool.
Preheat oven to 200c/400f (gas mark 6)
Add the olive oil to a frying pan over a medium high heat
Add the red onion and fry till softened and caramelized
Remove and allow to cool slightly.
When the sweet potato is cooled down, cut in half and scoop out all the flesh and add to the ground pork.
Add the onion and all other ingredient and mix well to all combined. You want the sweet potato mashed into the pork with little small pieces.
Form into equal sized meatballs and place on a baking tray lined with parchment paper.
Place in the oven and bake for approx 15-20 mins (pork should be cooked through)
Serve with your choice of sides, great with as they are or with sauce suggestions
For the sauce add the hoisin sauce, passata and water to a small saucepan and heat gently until thickened. Serve alongside the meatballs or drizzled over the top .
