In fact, it's very simple, I ate a similar salad in an Italian restaurant.
here are the ingredients:
Cut the meat into strips and fry (salt, pepper to taste)
Take a bunch of lettuce leaves, cut not very finely and mix with arugula.
We take an orange, do not peel it, but immediately divide it into 4 parts and cut out the soft part from it and the mode is also not very small.
After that, mix everything and add soy sauce (you can dilute it with a small amount of water).
