I've been making this salad heaps recently and adding a bit of sliced steak, chicken, lamb or whatever DH is wanting on top. I usually rub some chinese 5 spice and smoked paprika on the meat before cooking and place it on top of a salad of the following...I made it up one night with stuff that i had in the fridge.

In a big bowl (that you can eat straight out of - well you don't have to but DH doesn't eat salad so it's only for me anyway) I add...

Some mixed salad leaves - the ones with lots of rocket...
Thin slices of red onion
thin slices of red capsicum
thin slices of celery (in lengths not accross)
thin slices of snow peas
a few sliced mushrooms
and cut half an apple into matchsticks the same length as the other vegies

season with salt and pepper, add a dash of balsamic vinegar and a dash of extra virgin olive oil and toss together...add sliced meat on top...it tastes really good..

Sometimes i also add some nuts if i have them in the cupboard ie. walnuts etc..
