First of all, this is not a quick weight loss diet that you go on, buy some special food to eat for a month, and then go off. It's a permanent lifestyle change, so you need to learn to shop and cook this way or you'll just go off the program and gain all your weight back. It takes a while to get used to and adapt your shopping and cooking, but it will be better for all of you once you get the hang of it.
My family (husband and son) are not following SB, but I don't make separate meals at all. They have things available for breakfast and lunch (cereal, bread, sandwich meat, ramen), but we pretty much eat the same dinners most of the time. I grill or roast meats and seafood, so that part is the same. I make either a large salad or some kind of cooked veggies or both. Sometimes I have a salad and leftover veggies from another day, but often I'll have brown rice along with them. They like potatoes, so I'll do mashed ones for them, but if I'm putting anything in the oven they get a baked potato and I get a yam, or I chop up veggies and potatoes separately, put them on a cookie sheet, drizzle with olive oil, and roast them along with the meat of the day. Theirs turn out to be wonderful healthy oven fries or roasted baby potatoes and I have my eggplant, zucchini, cauliflower, asparagus, winter squash, or whatever. They usually have some of the veggies. If I'm making asparagus or something my son hates, he has raw veggies and dip or a salad or a small dish of frozen corn that gets nuked in 2 minutes. It doesn't take much more effort than cooking the way I did before SB.
The only problem we have is pasta. My husband is Italian and he eats white pasta. I'm not crazy about the ww stuff and really don't want to cook two kinds. Usually I'll make the white stuff and have a small portion with my meatballs and a large salad. Other times I make a small lasagna with those no-boil noodles for them and an eggplant lasagna for me (I roast eggplant slices on a cookie sheet when I've got the oven on). That takes more planning. We do eat a lot of Asian-inspired dishes and have buckwheat soba with them, or brown rice, both of which we all eat.
My son also does not like beans, so I make chili or bean soups for myself and my husband, but I mostly have them for lunch. I make a big pot and then freeze individual portions so I can have a warm satisfying meal pretty quickly.
Once you find ways to fill out your menu with foods they like you'll be fine. It may take some weekend planning and cooking ahead for a while, but you'll be able to do it and eventually they'll start eating better, too. It's a great way to set a good example for your family.
