the ideea is to make a fine cauliflower puree which then goes in your kid's favourite pasta sauce. i've made this a few times to get it right, and for zhara it only works if i use a sauce mornay made with munchee - it's the only cheese she'll eat. we also use miniature pasta, she's just more amenable especially if they have cute shapes, like animal or letters.
i don't know if you can tell looking at the picture, but it's all bite size, the penne are less than 1 inch, and the meatballs are barely the size of a quarter. so first you break the cauliflower into small florets and you boil it until easily pierced with a fork. while it boils, prep your sauce and boil the pasta. you can either do a bechamel, by making a roux out 2 tb each butter and flour and then streaming in 1 cup milk, or you can use jarred alfredo sauce. either way, add to it 1/2 cup packed grated cheese. when it's melted add the cauliflower puree, season with salt and pepper and pinch of italian seasoning. i have to use equal quatities of sauce and cauliflower puree, any less sauce and she won't eat it. one cup sauce plus one cup puree is sufficient for 3/4 lb pasta.
zhara enjoys it very much. she ate so much of it for lunch that she couldn't touch her usual second course of fresh fruit. the meatballs didn't fly, but i don't care, this is still such progress for her!
