Hm, in college I would buy chicken thighs and throw some garlic powder and soy sauce on them, bake in a toaster oven. Delish.
If he has an adequate kitchen, I would like to share my 3-day chicken plan:
Take whole chicken, cut out spine with a pair of strong scissors. Spread out on a broiler pan. (These are usually in the bottom drawer of the oven and no one knows what they are for.) Rub inside and out with oil, salt and pepper. Bonus: Cover the bottom of the broiler pan with aluminum foil for easy clean up. Slice up some potatoes and onions and lay them in there. Rub with oil, salt, pepper. They will cook with the drippings.
Meanwhile, take the spine and anything else that came in the neck/giblets packet (minus the liver), simmer in a pot with some onions and carrots or whatever he likes. When the whole chicken is done in the oven, pour the drippings in this pot for extra flavor. (He can also wait until a later day when he's removed all the meat from the chicken and use the whole carcass for stock instead. That will be more flavorful. I just find doing it the first day while you're waiting for the chicken to cook saves time.)
End of day 1: Eat as much chicken as you want.
Day 2: Cook some pasta in the stock. Add however much chicken you want. Eat soup.
Day 3: Cook some rice. Throw in a can of black beans and some frozen corn. Add some oil and the rest of the chicken and any spices if he wants. Add cheese on top if desired. Eat casserole.
Agree with apennysaved that chicken salad sandwich is a good option if he still has leftovers. Just cube the chicken, add some mayonnaise and put on bread.
