In fact, it's very simple, I ate a similar salad in an Italian restaurant.
here are the ingredients:
Meat, cut into strips and fry (salt, pepper to taste)
Take a bunch of lettuce, cut, not very finely, and mix with arugula.
Take an orange, do not clean it, and once the mode of 4 parts and cut out of it the soft part and the mode, too, is not very small.
After that, mix everything and add the soy sauce (you can dilute it with a little water).
