We went to New York and Washington DC a few weeks ago and I too asked forum members for advice, particularly regarding lunches. We found loads of delis and health food stores in New York where you could either purchase ready made salads (with dressings served separately - often in sachets with nutritional info) or make/order your own. When we stayed just outside Washington we found supermarkets that also did this.
Restaurants were very accomodating and would swap carbs for veg. Be aware that if you order a meal with a side salad this comes first like a starter.
It's probably wise to buy something to eat on the flight as what we were offered was carbohydrate overload!!! -
BA Lunch was Butter chicken with rice or pasta in cheese sauce
with cous cous and a few token leaves, bread roll and a pot of fruit posset (I think) - didn't eat as too many carbs.
Tea was a chicken salad sandwich with a chocolate biscuit.
AA Dinner was Chicken in mushroom sauce with rice and a few token veg, small salad and may have been a bread roll. Then, I think a chocolate brownie type thing and cheese triangle and crackers.
I think breakfast was fruit juice and a Danish pastry.
