Boil the sweet potato until completely soft, about 15 minutes, then drain.

Meanwhile, cook the turkey mince in olive oil over medium heat until fully cooked through with no pink remaining, breaking it up as it cooks.

Combine the turkey, sweet potato and stock in a blender.

Blend for 2-3 minutes until fully smooth, adding extra stock a little at a time if too thick.

Pass through a sieve if any texture remains.

Serve warm.
