ooh - thanks for that - will have to give it a go! 
Redridingwolf - good luck with the project - sounds like a really good plan. My favourite meals are those which are naturally gluten free anyway - things like:
Chilli + rice - the boys also love this (they're not coeliac - just me!)
Chicken kebabs which your ds might like? Chunks of chicken + any veg chopped up on kebab sticks, marinated if you've got time in a mix of Tamari sauce (just like soy sauce only gluten-free - you can get it from big supermarkets), honey/sugar, balsamic vinegar.
Stir fry pork/chicken - with rice noodles - chunks of chicken fried in a wok with veggies
Gluten free spaghetti/pasta is OK when it's first cooked so a good old spag bol is good - but I find gf pasta isn't great cold - best avoided!
Cottage pie/shepherd's pie solves that problem as it's mash on top instead.
some gf pizzas are OK and certainly if ds's were coeliac they would want gf pizza once a week 
When we're having Mexican for tea, I have the taco shells as they're gf - made using corn - so means I can join in while the rest of them are having wraps.
eggs come in very handy for lunch - poached/boiled etc. with bacon - lovely!
I tend to avoid gf bread completely as it's usually disappointing - Genius is about the best you can get but I've just stopped eating any bread now. Corn cakes are good if I want something like that though - with anything spread on it.
Oven chips are mainly OK - the 'ordinary' ones - some of the french fries type chips aren't gluten-free so check carefully. But last night we had steak and oven chips which was lovely 
Hope this helps - will keep thinking of gf meals which might be tempting
