Ok then I'd go with the other suggestion. Get him a small GF pizza and then super yummy regular for everyone else. And only let him have that GF while everyone else enjoys the yummy other stuff.
I will do this. I don't care about the price difference.
Although I might pick up something really awesome for dessert that has gluten in it, just to see if he tries to eat it. And get him some fruit
And if he does, make a big production out of refusing him. "Oh no FIL! I couldn't possibly let you eat this! I care too much about your health! I know how dangerous it is for you to eat eggs and gluten. Enjoy your apple slices!"
I'm coming into to just say that gluten free pizza isn't terrible, depending on where it comes from.
Garlic Jim's and Domino's are actually pretty good.
And DH has to order it without cheese. And it doesn't suck.
I will say that I still order my own cheesey, gluten filled pizza. While the gluten free doesn't suck, regular pizza is better.
You speak the truth. There's a new restaurant in my town with a homemade (NOT frozen cha ching!) GF crust and I want to just fall over and die it's so good.
They went full on gluten free before Thanksgiving two years ago...and we were hosting. So, I spent an hour at Whole Foods trying to get this whole gluten free thing right (along with another woman who I ran into in every section doing the same thing - eventually we just got our own stock boy and did it together) and we made a full Thanksgiving dinner gluten free for their suddenly Celiac whole family.
Turns out gluten is yummy.
So, then they were allergic to dairy. And he'd go to the coffee shop and turn down all things and the barista would be all "but sir - this is soy" to which he'd respond "I know - I'm dairy free - can't eat any of it". Huh.
So, dairy is also super tasty so it turns out that they aren't all suddenly allergic to dairy.
Eventually they settled on potatoes. They are the cause of all of the ills and learning disabilities. Wonder what'll happen when they start to miss french fries?
But as a gracious host, you can accommodate his asshattery while sharing with us.
I'd buy him a frozen pizza and buy really good real pizzas for everyone else. Offer him a little fruit salad for dessert and gluteny goodness for everyone else.
I have a niece who does the diet de jour- sometimes raw, sometimes vegan, sometimes low carb, prescatarian, dairy-fee, locavore- and then she goes on vacation and posts FB pictures of her eating pork in Portugal. I've given up, I cook she eats or not. (fwiw, she lives with me so it's kind of a daily thing)
Between the portrait and the faux allergies, he sounds like a cross between Tony Soprano and my former MIL, who faked a black pepper allergy for attention, and when that got too complicated, switched it over to onion.
The portrait over the fireplace is classic. I love this so much.
My ex SIL has a huge portrait of herself over her fireplace; first thing you see when you come in the house. lol
I'm due to be getting a huge portrait of my mother. When she lived here, it was over the fireplace and there it shall return.
It was painted by a recognized mid-century artist with whom she was friends and who died less than a year post-portrait. She was pregnant with me at the time though he did not paint her as such, he painted her as she would look at 40 because he said it was unseemly to paint a 19 year old. Most people who see it assume it's me. DS can't be convinced otherwise. When it hung at my grandparents' house they hung to be visible from the yard to discourage burglars. I don't know if that's funny or insulting.
I'd get him like a 6" GF pizza, then laugh as he makes sad eyes at everyone else enjoying theirs. There would be pizzas on every flat surface, as far as the eye can see.
Then I'd arrange for a delivery every 45 minutes or so over the course of the evening, and make a big production out of answering the door every time.
He could always have a couple of muffins if he's still hungry.
