My wife has been pretty good about allowing me and the kids to have pasta and bread occasionally, as she will will just substitute gluten free pasta and bread. The really hard thing for me is no pizza. I really miss the occasional friday night pie, and I wouldn't dare eat it in front of her. We went to a burger joint in Burlington last weekend with a bunch of hockey families after my son's game, and it was sad watching my wife eat her cheeseless meat patties with a knife and fork.
It has been tough. It's all the things (e.g., seasonings, sauces, etc...) that you don't think about. Meat and veggies, meat and veggies, meat and veggies.
