So did my grandmother. When Grandpa sold the farm and moved her to town, she discovered store bought foods and never looked back. lol
My Grandma found ‘Hamburger Helper’ a revelation :-)
(Of course, she was doing her best in her ‘sixties to largely raise a couple of kids on a shoestring.
(For ‘fancy’ occasions, the little frozen puffed-pastry patty shells filled with creamed chicken were her go-to; and I still love that.)
My husband just remembered that one of his grandmothers really liked ‘boxed prepared foods’, and when they went to her house, the kids really enjoyed Rice-a-Roni.
When his mom noticed how much they liked it, she recreated it at home, from scratch - she was also raising a bunch of kids on her husband’s school-teacher salary, and figured out how to stretch a dollar!
