People try to make steak into budget protein and then feel cheated, or they make chicken into a steak night and feel bored. Chicken breasts are the volume protein. Beef steaks are the plate you wanted. At Meatsupermarket.com you can put both in one order. You should not pretend they are the same number.
Chicken as volume
Fresh 5kg Chicken Breast Fillets or the frozen 5kg is a lot of protein for a freezer. Portion it, grill or air fry it, log it if you must. It will not eat like ribeye. It is not meant to. If you need cheaper still, legs and misshaped dice undercut breast. Breast is the neat log. Legs are the thrift log. Both beat fillet steak as a cost-per-gram story.
Rump Steak 8x 6oz is a week of steak nights and a worse protein-per-pound than the chicken bag. It is a better Tuesday if Tuesday was supposed to be steak. That is allowed. Protein eating that never has a steak is how people fall off and buy a kebab. Put steak in the week on purpose. Pay for it as steak.
A mixed week that still hits numbers
Five chicken meals, two steak meals, one mince meal is a week a lot of training households can live with. Shop high-protein meat boxes if you want that mix packed for you. Shop loose if you want to control every gram. Neither is morally better. The mixed week is just more likely to get cooked than a pure chicken month.
Stop converting everything into chicken
A sirloin does not become a good chicken substitute by being sliced thin. Eat the sirloin. Log it. Move on. The money question is only useful at the point of the basket, not at the point of the plate. Once it is cooked, it is supper. We sell both because both belong, and because a butcher who only sold chicken would be a different shop.
If the month is tight, grow the chicken and shrink the steak, do not grow a story about cheap fillet. If the month is fine, buy the 8x rump and stop calling it a macro strategy. Honesty at the cart is the whole of protein-for-the-money, and it is more useful than a chart you will not look at while the pan is hot.
Keep sides simple so the meat can be the cook: potatoes, greens, rice, a bun. A pack is not a tasting menu. If you attempt six projects, the meat will be the thing that goes grey while you chop. One good cut, two sides, sit down. That is as true of Chicken vs Steak: Protein for the Money as of any other pack we send out of the cutting room. Cook it like the cut it is, and it will earn the next click.
