My husband is also coeliac since he was a teenager. I find it easier for us all to be gluten free to avoid cross contamination and lots of food is naturally GF, eg meat/ fish and vegetables and potatoes, you just have to watch out for predictable culprits like gravy when you eat out (although lots of places have GF gravy as standard). Lots of places are great for GF, especially in the lake district and some even do GF fish and chips (separate fryers) and GF roasts as standard. Legally all cafes and restaurants have a list of allergens in their food which makes life easier nowadays.
Apart from puff pastry, there isnt anything I haven't been able to make GF, even profiteroles. I follow non GF recipes and use Doves farm SR flour that has xantham gum in and ensure that there enough eggs in the recipe (i usually use 3 for a cake for example) as they really help with binding and raising. I found that Gf recipes didnt work that well for me but that's a personal preference.
GF pasta- we prefer the ones made with rice flour rather than corn (Doves farm again- i dont work for them, honest!) and you have to cook on a rolling boil and stir every now and then to stop it sticking
Noodles- rice noodles (flat white or vermicelli) are naturally GF and essily available in supermarkets
Soy sauce- can get GF Tamari which is a Japanese soy in all supermarkets
Bread- Newburn bakehouse (Warburtons) new artisan loaves are amazing and just like non GF bread or wheatfree bakery (link in earlier post) or Schar (esp ciabatta rolls)
Pastry- i make with doves farm sr flour and use 1 egg to bind instead of water and roll between 2 sheets of greaseproof paper or press into a tin or Schar do a good frozen version
Sausages: sainsburys (3 of their taste the difference range are GF) or M&S do lots of GF sausages and apparently do some GF ready meals now.
If your husband is anything like mine, he will like beer. The good news is that there are quite a few around and some pubs sell them too. Sainsburys sell Greens golden ale and Greens lager and Estrella Daura lager and other supermarkets i think also sell some and there are several other brands as well online.
When we go on holiday we usually take some Schar ciabatta rolls and toaster bags then he can have those with eggs etc. Watch out for cereals, even some cornflakes have gluten in. Schar is a continental brand so we can always manage to find it when we are abroad and their range is pretty extensive. Italy has the highest rate of coeliac disease and we were surprised that lots of restaurants there have GF menus. Otherwise you can take little cards (or get them on your phone) that has a translation to say that you need GF diet.
Once you get used to it, it is pretty easy to follow a normal lifestyle GF and not feel like your husband will be missing out. Patisseries in France are the only place that induces a degree of envy and longing for my husband hence I've worked on my baking skills to try and fill that void.
