Yay! Congrats to your brother!
I have a few suggestions.. I don't know if you're in to veggie burgers or stuff like that, but they make ground veggie meat (I don't know the correct name) that you don't even have to defrost or anything, I'm not a vegetarian, but I hate cooking ground beef, it's so ucky! You can plop that in some spaghetti sauce, or use it for tacos or anything! Also - Taco Bell makes some great taco kits, it has the seasoning in it and everything you need. He can even buy the chicken already cooked & cut in strips, too!
Also - Betty Crocker or a company similar makes these kits where everything you need for Chicken & Dumplings or something like that is included... you might have to mix the dumpling mix with water in a bowl, but after that one pan is all you need!
Sorry - that's all I got! Best of luck to him!
