This is where it’s okay to be sneaky … I had fussy children and they never guessed that the ‘potato’ topping was actually butternut and sweet potato. Winning!
Place the basic bolognaise, peas, corn and carrots into a heavy-based saucepan over moderate to low heat and bring to a gentle simmer for 10 minutes or until the veggies are cooked. Set aside.
Boil the sweet potato and butternut in just enough water to cover (adding more if needed) for 20–30 minutes or until cooked through and soft.
