I've been living frugally for almost a decade now, grew up in a family that was frugal even when we lived in what I now understand to be upper middle class. That was passed down from my grandparents on both sides, who were children during the hard times between WW1 and WW2, and parents during WW2, on opposite sides of the war.
My mom's family is from Alberta, and I'm just 3 generations back from farmers on that side: my grandmother grew up on a farm, and remembers her mother, smeared with blood and feathers, telling her never to learn how to clean a chicken, or she'd be cleaning chickens for the rest of her life.
My dad's family is from Vienna, Austria, and our farming roots go at least another generation back, to what's now Czechia, and was then part of the Austro-Hungarian Hapsburg Empire. During the war and after, the family would visit and summer in a rural village, working for their board. It was hard to get fresh, good food in the city, and a much nicer life in the country, so nice that one of my aunts married a local boy and lives there still, a grandmother.
I could go on, but my intended point is that I was raised frugal but urban post-agricultural, a city boy, and want to share/swap some cheap feast recipes.
