If we go out for pizza, we have started getting an antipasto or garden salad or some kind of salad before the pie, amazing sometimes there's pizza left to take home...lol
If we're at Uno, I might get 2 sides of roasted veggies, or veggies and that brown rice dish (not a huge huge fan, but it's better than smashed potatoes with cheese, etc.)
At Taco Bell for lunch we got the cantina bowl, it was really good, not sure about the nutrional info, but it seemed better than getting that burrito with the fritos inside or crunchwrap thing...
I also try and order at least at some point a glass of ice water with my meal, so I get some of my water in...
also, if you find yourself at a chinese buffet, if you look around there are quite a few veggies there, you can load up on them and not so much of the batter dipped things and still very tasty, I always make sure I get some soup, too. that way by the time it's dessert time I'm too full..
I find myself actually looking at the "light" entrees and seeing if something there interests me, at a greek diner I had a fabulous grilled chicken salad with dressing on the side, I mean fabulous...
best of luck...
