Ditto what several others said. My kitchen is gluten-free, but my husband is not. He has tried to go completely gluten-free before (of his own choosing) and he always gives in to temptation. So he just eats gluten when out of the house. When we go to friends houses or restaurants (although rare) or if he is at work or traveling for work, he eats whatever he wants. The only rules are he must brush his teeth before kissing me, wash his hands after eating and not touch my food. I will sometimes offer to share food or offer him a bite of something I order that is gluten-free. He has learned however to let me put it on his plate for him and not to reach over and grab some of my fries when he has been eating a burger with a bun. There are actually a few places we eat out where he will get the same thing as me so it happenes to be gluten-free. He loves getting a protein-style lettuce wrapped burger at Red Robin. However, I have not gotten him to willingly order gluten-free pizza. He will eat my homemade gluten-free pizza crusts (and he says they are good!) but if we are getting pizza from a restaurant I am getting the gluten-free/CF and he is getting a regular one. So pizza for two is much, much too expensive to do very often.
I have tried a gluten-free pizza. It is a decent alternative to nothing. They are not cheap and a $10 10 inch pizza just isn't enough for me. I ordered a gluten-free pizza at a restaurant after a lengthy discussion w/ manager about why my pizza was gonna be an additional $5 for the same type of pizza vs. a specialty gluten pizza. I understand that the crust can be more costly but if I had ordered it as a build my own, it would have been $1.50 difference. Sorry about ramble, but the point was I still received CC and 20 minutes after eating it, I had major problems. It's tempting to almost eat the real stuff and deal w/ consequences anyway.
