Some of ours ... I can't tell if these are manifestly obvious or things that are very habitual for me but maybe not so much for those raised differently or during different eras, so here goes
*think 'filler'- we serve things with meat IN them rather than, like, a cut of meat. Tons of ways to do this deliciously and healthily, from "hot dish" casseroles to one-pot stove top cooking to omelettes/frittatas to burritos and enchiladas
*We let the instant pot or crock pot do what it does best, buying cheaper, less tender cuts that need to be slow simmered for a long time, put them in with liquid and spices, and then enjoy barbecue sandwiches, chicken tinga, etc.
*We wait to plan meals for the week until we've gone to the store and seen what is fresh and cheap for both meat and produce, and then we build around that. This prevents disappointment if you can't get there in time to grab an advertised special, but does take some background cooking knowledge and self-restraint. We have those.
