My daddy swears by this skillet that feeds 6 and costs under $6 to make. It is still the cheapest hearty supper I know.
Nana stretched about $8 of groceries into supper for 8 with this layered bake, and nobody ever went back home hungry.
My grandmother fed a table of 6 for under $7 with this every September. Just 4 ingredients and the whole pot was always gone.
