Unsure if you're looking to actually reduce calories for other family members? But presuming you're not -
I tend to do the same as BillieWiper above - just give myself less carbs/more veg.
For example:
Casserole - chicken, loads of root veg, lentils or pearl barley. Serve with a load of mash or add bread for DH (just casserole for me).
Bean and chicken chilli - big batch made in slow cooker. Add rice/wraps/couscous for DH, just serve with extra veg for me.
Lentil bolognaise - make batch in slow cooker. Serve with rice or pasta and cheese for DH, serve small portion of carbs for me, or just veg, and measured amount of cheese.
I also do a feta bake in the oven - feta, olives, peppers, tomatoes, lemon, garlic and herbs. Could add chicken or fish. Serve with couscous or bread for DH but no carbs for me.
My tip - weigh out your own portions for things like cheese, as it's really easy to eat loads of calories when you judge it by eye.
