rice flour works well to replace wheat flour in most recipes, xanthan gum powder is a good thickener, remember rice flour has no raising agents, but you can add g/f bicarbonate of soda or g/f baking powder to aid rising.

try mixing half a tsp of baking powder with rice flour and enough water to make a dough, heat a frying pan with a drizzle of oil, place the dough in the pan and flatten out with a spatula , once golden on the underside turn and cook the other side....quick simple flat bread

try making pancakes by replacing the wheat flour with the same amount of rice flour and baking powder

carob is an alternative to chocolate, but i prefer to kneed quite a bit of cocoa powder into fondant icing, it can be rolled out and cut into little squares or rolled into balls and rolled in cocoa or left plain. chocolate hit without the gunk! hot milk with cocoa and sugar also hits the mark

gluten is in all sorts of things as it is not just bread and wheat cerial that contain it. it is used to keep stuff like powders, ground up nuts, oats etc from clumping. it is also a bulking agent so things like sausages and burgers also contain gluten... try mixing ground pork with crushed rice cakes, egg and herbs/seasonings shape into burgers/patties, coat in rice flour anf shallow fry to seal before cooking like normal burgers.
it is a thickener used in gravy and white sauces - either make your own or buy a G/F version

cakes, biscuits also often contain gluten, even some sweets do too. look up a fatless sponge recipe and replace equal weight of wheat flour with rice flour, it works, i know! this mix can be made into a jam/jelly filled cake(victoria sandwich) swiss roll, sweet flan case, sponge fingers for trifle or tirimisu, fairy cakes, and much more.
things coated in breadcrumbs usually contain gluten, though i do buy free from fish fingers which are g/f and are yummy!
pastry egg noodles and pasta are made with wheat flour so contains gluten. but you can buy rice noodles and pastas in chinese supermarkets which are a good alternative if you have a decent sauce with them.
often frozen chips and roast potatoes have a coating to make them crispy, this contains gluten, the budget ones are less likely to be coated!

you may want to lower your cheese intake as well as your chocolate too as it is renowned for causing migranes

you can make dairy free cheese by grinding cashew nuts to a paste and mixing with a little marmite or vegimite.. great for flavouring kale crisps

eating out i tend to stick to steak and salad or roast dinner with gravy on the side
gluten is in barley too so many beers contain gluten. stick to wine!
