There is a book called “Grandma’s Wartime Kitchen” that has some economical meals made with less.
My husband and I both pack our lunches. I take leftovers and he takes lunch meat, cheese, fruit and vegetables. If we went out every day, that would be at least 30 per week for each of us = 60.
I almost NEVER eat out - it’s a budget killer. If I’ve been out and around for awhile and I’m hungry, I’ll get a couple of Wendy’s dollar burgers. I can’t remember the last time I ate in a restaurant - I can feed myself for two days for what a mundane restaurant meal costs.
