My DH loves the high fat side of it, but not so keen on the low carb! So for him and the kids I often cook them roast potatoes, or pasta and just don't have it myself. They also eat bread. We have been sugar free for years, and so I haven't bought a lot of processed foods for ages, so not a huge change for us.
Would your DH have coconut milk/cream? Or you might like to look at some Paleo recipes as they are often LCHF, but also dairy free.
Edit: our dinners usually consist of meat and veg, lamb chops/ steak, sometimes with a creamy mushroom sauce, also do a chicken schnitzel or chicken wings with an almond meal and spices crumb (DH thinks it tastes like KFC), we have a roast once a week (chicken, pork, lamb or beef) so DS1 has something to put on his sandwiches for school lunch.
I make a cauliflower pizza, and then just make a normal pizza base for DH and the kids (although I try to get them to try the cauliflower one too).
I have bolognaise sauce with zucchini noodles, really a lot of things you already eat can be made LCHF 😀.
