You have to "think outside the box," to erase your ideas of dinner being "meat and 2-3 sides" or even "a main dish plus sides." Instead offer your family 2-4 meatless selections and let them figure out for themselves how to not starve, you know? If there is vegetable fried rice, roasted Brussels sprouts, cole slaw, and boiled eggs to choose from, surely there's something for everyone? And the leftovers are such that they can be recycled into a future meal, not thrown into the waste bin, yes? And of course there are one pot meals, like a soup or stew with a raw veggie & cheese plate, like pasta primavera with salad, like green bean casserole with baked sweet potato, like stuffed peppers with a side of cabbage?
