How do you deal with eating out?

Just got back from a trip to Santa Fe & lost 5 pounds in a week! I ate
salads, salads & salads. We ate 2x/day. When I ate breakfast I had
scrambled eggs and ham, no toast. I had salads for dinner & lunch though
2x I had fish/baked potato/veg. I drank water, water, & water. I did
make sure that I had salads with no cheeze & tried to get reduced fat or
low cal dressing. Baked potato was with no butter. Being on vacation, we
walked constantly!

Finally, I tried to not finish meals. Leave some on the plate.
