sweet potato, parsnip and butternut squash baby recipes

[2bmum]

My lo is not keen on savoury food, he'll eat it but it's begrudgingly. The ones he does like though are butternut squash, parsnip and sweet potato. Other than roasting and mashing them, what else can I do? Ideally recipes that I can have with him but if not just baby ones. Doesn't matter if it's a combination of all 3 veg or just one or two or has over veg as well as these in it. Veggie friendly recipes too please. Any suggestions welcome
