Say you go out to eat with friends or family. They picked the place. You look at the menu and everything is either deep fried or breaded or ON bread. No plain steamed veggies and a chicken breast here! Or even if there is, maybe you want something a little tastier. Most places these days *do* have a salad or two on the menu, but they can be pretty meager. Maybe there's a "side salad" which is just bagged iceberg and shredded carrots topped with croutons and cheese. But most places have better veggies back there! You just have to be creative.
Look at the sandwiches or the burgers or the tacos. Do they have lettuce on them? Often it's Romaine, or even spinach. Look at the other things they list on their burgers and sandwiches: sliced tomatoes, onions, mushrooms, avocado? Sounds like a salad!
You can pick any item on a menu and just ask, "Can you make that a salad, please?" and almost everyone will accommodate you. If they look puzzled, just say, "no bun (no bread/taco shell/tortilla), just put it over a big plate of lettuce, tomatoes, onions..." and whatever other veggies you'd like. A bacon avocado turkey burger is fantastic over a salad! Or how about a ham and turkey
Who needs bread anyway? I don't! We don't need buns. We don't need tortillas. No need for taco shells or pitas or crusts. A "pizza salad" full of lettuce, tomatoes, onions, mushrooms, peppers, black olives, ham, pepperoni, and cheese is so good. Eating low carb can be delicious... and easy... even when you're eating out, if you know what to ask for.
