I am not-quite-vegetarian normally. I eat poultry & fish (no mammals) but DH is fully vegetarian and 95% of the time I eat veggie. When I do eat meat it's limited to eg a scattering of prawns on a veg pizza or adding some chicken into some leftover veggie tagine when there wasn't a full serving leftover.
I have a medical procedure next week in preparation for which I have to eat absolutely nothing that contains fibre for 3 days. Pretty much no veg at all except no-fibre carb things eg skinless potatoes and white rice etc. I can have chicken, fish, cheese, white carbs etc but I have no idea of anything I can do with this other than a bland and flavourless lump of protien on bland and flavourless carb - everything I can think of that gives flavour and depth is on the "not allowed" list. I would love to have some fish with a yummy salsa verde of other veg sauce but I can't. I can have Fish&Chips one night and that will be nice but I have 2 other dinners and 3 lunches to come up with
