roast a bunch of chicken legs. hard-boil eggs. make crustless quiche. cook big hunks of meat in the slow-cooker or a dutch oven. pre-chop carrots/celery/cukes/daikon for quick salads. make big batches of meatballs.

make chicken liver pate, portion and freeze.
basically? batch-cook stuff you like and freeze it so he doesn't have to deal at the last minute since his skills seem pretty minimal.
