I got the good luck. I remember not really knowing how to cook anything except cookies and never cooking anything of substance when I had an apt. I would ask for my mom's chili when she came--then once she told me how easy it was to make in a crock pot--I had no idea.
So, in addition to sending a few frozen things, I would encourage the crock pot for your son. I would make all of these listed below at home before he goes off to college, and show your son how to make it, make an extra batch while you are cooking to freeze and take to school (so they guys can see how good they taste--and be motivated to make them again) and also then stock the ingredients for a few simple recipes. Here are some easy ones:
Sweet and sour meatballs (chili sauce, grape jelly)--we buy costo meatballs.
Boneless ribs with garlic, ginger (powdered is ok) and terriaki (sp?) sauce-serve with rice--send the rice, so they have it.
Chili--you can send frozen 90% meat with chili packet, can of tomatoes, can of beans, can of corn. I cook frozen meat in the crockpot on high for 1 hour, chop it up and dump everything in and cook on high for 2 hours, then additional time on low. They can also add spaghetti to it to stretch it out.
And, of course, spaghetti sauce.
