I use a lot of the same ingredients over and over (like you) but I mix up how I use them a LOT.
I cook very "Italian"... meaning I often roll one meal into the next (regardless of what the ethnicity is). When I smoke or slow cooker a pork shoulder one night it could be smothered in bbq sauce for pulled pork sammies, the next it might have lime & garlic drizzled over it for tacos... the remainder goes in the freezer, and the next week it gets brought out for vietnamese sammies, and the day after more goes in a pot of chili.
Meatloaf gets served at meatloaf one night, but gets stuffed into peppers on another, and rolled into meatballs and frozen for pasta one day next week.
Soup is soup one night, then cooked down for pot pies (or shepards pies) for the next night, and the remainder of the pies is frozen for days or weeks from now. Leftover potatoes get reinvented as those shepards pies, or might get kicked up with some garlic and ginger, or stuffed into samosas with some peas and spices.
