I feel your pain OP. Mine has just got progressively worse since I hit 30. There's no going back to my gluten-full days. Never again. The agony of gut ache just isn't worth it. My stomach has grown it's repertoire into an intolerance of onion/pickles/nuts/virtually all fruit except melon/certain roast veg/eggs/cow milk protein/fructose/anything high fat as well as gluten. YAY.
It's fillet steak and rice for me forever 😅
A few tips just in my experience..
Shop bought GF bread is horrid
Not much better for pizza
G/C cereal/biscuits are pretty good
Lindt chocolate balls have gluten in them!
Some Fish and Chip Shops will fry their chips in GF oil if you ask. I'm fine with those.
McDonald's fries are GF! Yay!
Dominoes do a GF pizza. But not much better than shop bought IMO
Most frozen oven chips are GF but always check the label. Cheesy chips for you when the kids have pizza?
The baked chicken with tomato and cheese on top that a PP suggested is very nice, I can vouch for that!
If your intolerance gets worse, get very used to checking labels. You wouldn't believe how many products have gluten in them. I couldn't believe how many types of sweets are not GF.
Peppermint colpermin are your friend 🙂
