The dessert masterpiece! - chocolate fondue (use chocolate as bitter as tolerable for five year olds) - dip with nuts, strawberries. mandarin pieces, apple cubes. bananas etc.
The sweetness of the fruit will counter act the bitterness of the high cacao chocolate too, and the kids will be so excited, they won't notice.
Another snack - Avocodo oil potato chips?
Sure the suggestions are not perfect primal food, but its a pleasant "cheat" for the kids and it is a special occasion.
5 year old vegetarian kids? for some reason that is the saddest thing I have heard today!
Fear of the unknown...They are afraid of new ideas. they are loaded with prejudices, not based upon anything in reality, but based on… if something is new, I reject it immediately because it’s frightening to me. What they do instead is just stay with the familiar.
