How to make
Heat olive oil and add the finely chopped onion. Add the ground walnuts and fry for about 2-3 minutes.

Add the water, mix well and add the resulting mixture to the walnuts and onions.
Season with black pepper, oregano and as much salt as you like and cook to the desired thickness. Remove the prepared sauce from the heat and sprinkle it with finely chopped garlic.
You can serve this sauce with a roasted fish of your choice.
