I have a vegie fussy child. I will grate cauliflower, broccoli, zucchini, carrot etc extra fine and freeze it in snaplock snack bags. I hide a bag in anything I can, like home made burgers and even home made nuggets with cauliflower hidden in them. Spaghetti bol gets 2 bags. A white pasta sauce will get the pale vegies hidden with lots of herbs to hide them. Zuchini slice becomes egg and bacon slice and the green bits I say are herbs. Blended soups work, as does putting some cheese sauce on top of some steamed veg. Alternative textures and shapes, spiralised carrot and zucchini noodles, However it gets in!
