Hi Leenia, it seemed simple to google something like: "Learning how to cook for teenagers" or "healthy recipes for teenagers" to find lots of resources to check out and find something suited to your grandsons needs.

That said, learning how to buy food is probably even more fundamental than cooking so the search I did using the phrase above gave me this link: http://www.thekitchn.com/step-one-buying-and-storing-food-222973   for starters.

One other thought, can he cook anything? Is he good at one or two things? Why not start with his strengths and build on what he can do if he has any in this respect? Nuff said for now.

Cheers,

Andrez
