I would say be careful of the salt and sugar content in processed foods.

When he starts making soups, chilli, stews, sauces I would advice doubling or even quadrupling and freezing portions so he can reheat at convenience. when making try to steer clear of adding salt. If there is a Kroger in his area, Zesty Blend original is a fantastic salt substitute. Just a blend of dried herbs and orange zest. Love it on fried potatoes, onions and bell peppers.

Eggs once or twice a week, omelet with brocolli and cheese or as we did yesterday with sauteed onion, red pepper and mushrooms and a dash of soy sauce to make our own foo yung.

pre-made crepes or flour tortillas filled with anything (couple of spoonfuls of chilli or stew) is quite easy.

best of luck and healthy eating to your friend.
