I do sweetcorn, carroty and courgette fritters, called 'sunshine fritters" or "traffic light fritters" depending on which veg are in them.
Banana (and choc chip) muffins.
Scotch pancakes, very little sugar in the mix, but blend in a banana and a grated apple. Serve with blueberries, or drop blueberries on them when cooking.
Crumble - sweet and fruity , or savoury, cheesy and veggie.
Red sauce - basically a ordinary tomato sauce, with a sweet potato added (fry an onion, mix in two tins toms, half a chopped sweet potato) and any other veg you have. Cook til all veg soft, blend, blend, blend and strain. Serve with pasta and meatballs.
Both DC will eat raw mushrooms and consider them a treat!
Falafel.
Corn on the cob.
