My kids are the same, and it all got a bit much with homeschooling and all (I use cooking for a few crossover subjects) so they're allowed to cook one thing with me a week - and they can choose whatever they like so its like a treat. We've made cupcakes, jelly, pizza, cookies, cheese toast, turkish pide, they make their own salads too now lol easy stuff but still helping out nonetheless.
