LOL - gotta train em up young ... I will admit I do not serve brussel sprouts cause they STINK so nasty I myself have never acquired the taste and am trying to figure out how to make the Kale chips so that they are indeed 'chips' for them to try but have been hiding some cut up tiny in our 'baby greens' salad with the spinach and romaine ... but the rest I serve regularly cause I myself do not drink milk or eat a lot of dairy outside of 'hard cheese' so need to get calcium in my own diet.

Rhubarb is easy to hide in 'applesauce' BTW and in muffins with another fruit like Strawberry or something so they do not know they are getting it ...and it freezes nice over the winter and is often FREE if you have a friend who grows any they are always looking to get rid of it cause it is a weed that takes over everywhere - my MIL provides me with tubs full.

Other things I admit I 'hide' in pureed veggie sauces in stews and pasta sauces or I make salad dressings from scratch and hide 'pureed veggies' in with the seasoning and oil ...

Please things like tofu have no 'flavor' itself and if you get the 'soft' stuff it will blend into a cheese sauce for noodles....just gotta be careful with too much tofu as a replacement cause it is high in natural estrogen and well too much of that is not a good thing in a diet either

Salmon & cream cheese wraps are yummy - chill them and cut them 'bite size' and serve with toothpicks with other bite size items like cherry tomatoes or diced peppers, cubed fruit to make em fun to eat. Also hide it in casserole like 'tuna casserole' only with salmon. Also can make nice 'fish sticks' with them - salmon patties on a bun.

Grind up the nuts in the coffee grinder to make 'flour' out of them and swap out a cup of regular flour for nut flour...add in some flax seeds or sesame seeds too and they cannot tell the difference between the texture of the 'nuts' and the seeds.

When someone picks that the menu serve 'chicken nuggets' or 'fish sticks' because I cook from scratch I also add sesame seeds to the 'breading' for them to sneak some in there too .... gives them a nice flavor when they brown and the kids just get 'used' to them being in there cause they want 'chicken nuggets' or 'fish sticks' and well that is how those are served here so I can eat them too

I have been lucky - while I tend to always have 'one picky eater' on enrollment at one time or another the others have all be strong eaters who bring the picky one around ... however they either eat what is served or they go hungry until the next snack or meal
