The usual fix for mixed diets in one household is cooking two dinners every night. There’s a lighter way to do it — plan around a shared base, then split off what changes.
Pick meals that are naturally close already — a stir-fry, a taco night, a grain bowl — where the base (rice, noodles, veg) works for everyone.
Add the protein or dairy separately at the end (tofu alongside chicken, a dairy-free sauce on the side) instead of building two whole recipes.
Keep a note on saved recipes for who eats them, so planning next week is a filter, not a memory test.
Shared ingredients (the rice, the vegetables) should only appear once on the list even if they show up in multiple people’s versions of the meal.
