In an emergency I have been known to eat ANYTHING, including nearby children and old ladies.
So it is always good to have an emergency contingency plan.
KFC - original recipe chicken pieces, no fries. Pull the coating off the chicken, if you are feeling virtuous. I rarely am.
MacDonalds - (last resort, this one!) the biggest burger they do, no ketchup, and remove as much of the bun as you can unstick. the cheesy bite things are bad, but not as bad as the fries. They do salads. Somehow a Maccies Salad seems like more of an abomination than a burger.
Burger King - as with MacDonalds, but better, nicer and less like eating recycled pap.
Indian - Tandoori, Chicken Shashlik, Butter Chicken, onion bhaji, saag paneer, brinjal bhaji, maybe a poppadom, any of the kebabby type things.
Chinese - veg/meat stir fries, ribs, no rice, noodles or batter coated anything.
Subway - a footlong, with a high meat filling (not those godawful meatball paste things) and then chuck most of the bread. Again, they do a salad, but I wasn't impressed when I saw that they only stocked low fat mayo. I mean, that is an Offence Against Nature.
99 times out of a 100 I would avoid any of the above like the plague, but when The Hunger strikes, friends and family will frogmarch me into them rather than deal with Hypo Rage. I am told I get a wee bit tetchy.
