For lunches I dont buy lunchmeat since most of them contain nitrates and are bad for you not to mention expensive. I buy chicken breast usually boneless and skinless on sale and make chicken salad sandwiches with mayo and relish. I cook the chicken in the microwave, let it cool, then shred and cut it up. Very easy and my husband can eat it for lunch all week. Also, I make tuna sandwiches and egg salad sandwiches.
Between those three we can eat those several times a week. I think they save money over lunch meats especially the egg salad sandwich. If you have high cholesterol you can take out some of the yolk after the eggs have boiled.
