When we were first married we ate lunch together in our apartment (both still in school), then he graduated, we moved and I started to pack his lunches. I always packed two sandwiches, three or four homemade cookies, two pieces of fruit, chips and a drink until he started to gain weight (my dad always ate this much and did just fine) - then he told me he would pack his own lunches and has ever since and that was 27 years ago .
He does prefer leftovers and has had co-workers jealous of his lunches because they always looked so good! When we don’t have leftovers though, he packs a sandwich and fruit or buys at the cafeteria at work. I don’t keep a lot of lunch meats in the fridge because we don’t eat that much of it, especially now the children are all grown.
