Some folks call this one "garbage salad," but... ucchh. I can't cope with that. Let's never speak of the un-tasty name again. It's too pretty!
The great thing about a chop salad is that you can alter the ingredients easily according to what you have. Change the type of berry, add some cold pasta (like rotini or farfalle) to stretch your lettuce out (seriously), add croutons, use any kind of cheese, switch to beef, whatever. Check out the good stuff in this guy:
chopped turkey bacon
diced breaded chicken
I just whisked up some balsamic vinaigrette (1 part vinegar to four parts olive oil) with lemon juice, Italian seasoning, pinch of salt & pepper and a little sugar to taste, but this would go with lots of different kinds of dressing.
Chop your heart out! (Eyw, that's worse than the other phrase...)
