I find I can buy many bags of groceries but most of them do me no good until they are chopped, browned, sliced, diced, roasted, baked, simmered, boiled, etc etc. In other words, "some assembly required".
I buy 10# ground beef and add chopped onions and seasonings, then brown it all in a roaster in the oven. Drain and package in smaller bags. Some is seasoned with taco seasoning. At least the browning mess is out of the way. I use my Kitchen Aid mixer to make meatball or meatloaf mixtures. Much better job than me mixing with a big spoon.
