Slow Cooking
Sprinkle a packet of dry ranch seasoning over raw ground beef in the slow cooker with 3 other ingredients for a meal so creamy your mother-in-law will swear you spent hours
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.
