Oh my. I would come and have supper with every one of you. All the food I love. I get so fed up of never eating what I want to eat, I've lost all interest. DH is dairy free, and has been for 12 years after campylobacter from unpasteurised milk at his cousin's dairy farm left with with intolerance.
So none of my past staples, cheese soufflé, macaroni cheese, tuna pasta bake, pasta al fungi (neither daughter will eat mushrooms), pasta pesto - have to get the dairy free variety. I used to make a nice spinach soufflé but it tastes much better with some Parmesan cheese, DH likes the dairy free one when I do it but the rest of us not so much. If I'm feeling keen I'll do individual ones so I can do one for him then add cheese to the mix for the rest of us. We end up eating meat or fish nearly every night when I would like to eat much less meat but my vegetarian preferences often involve eggs and or cheese and he doesn't like eggs either and neither do the DC. 
Fish pie? Mum made such a yummy, creamy one with cheese on top of the mash. My dairy free version is perfectly nutritious and DH likes it but I find it very bland and not particularly nice.
To add to my woes DD 2 has lost weight and had a long chat with the nurse at the GP, she needs to put on weight. But I need to lose it! So I rarely make puddings, or bake cakes like I used to and then feel guilty I'm not doing them for DD but DH won't eat them and I shouldn't. I buy her individual sticky toffee puddings for the microwave, or make the odd apple crumble. I've got an unopened pack of Philadelphia which is about a month out of date in the fridge, I was planning to make a cheesecake and then decided to spare myself from temptation. (It's unopened - what's the verdict on usability? Might make that cheesecake for DD at the weekend and tuck in and forget about calories)
And at Christmas DD1 came home having newly converted from meat and two veg to vegan thanks to her new boyfriend. She did cook us a couple of lovely veg curries (his recipe!) and wanted turkey on Christmas day. But I didn't bother doing any ham like I normally would.
To be fair DH does more than his fair share of the cooking and I just eat what I'm given but I wish I could just cook what I want, eat that and lose a little weight.
I'd like to come home from work and have an early, light supper, omelette and salad, eggs florentine, baked potato and homemade coleslaw. But then we'd have to have three different meals. 
So one dairy free, one vegan, one high calorie and me who just eats whatever's going or uses up the left overs.
DD had friends over when it was my day off so I made a large lasagne, salad, fruit salad and the best chocolate cake. I was amazed how much they ate, they are all so slim. All the lasagne went, they loved it, and came back for seconds and thirds. They finished the fruit salad for breakfast and I made them all take a slab of chocolate cake with them to school next day so there wasn't much left to tempt me. I really enjoyed cooking for them and them all loving the food. I can't remember the last time I made lasagne as it is quite time consuming and I get as far as making the meat sauce, planning to leave some for DH to have before putting the rest into the lasagne then think sod it, we'll all have spaghetti bolognese, why bother with the cheese sauce and the layers when it's just DD 2 and me that will eat it?
