Thon Chtitha is a simple dish of gently braised tuna with olive oil, cumin, tomatoes and optionally with chopped parsley, garlic, onion, lemon juice, chili pepper, herbs and spices.
For this recipe, I used tuna in tomato sauce since I was already going to use tomatoes in the sauce. You can certainly use tuna packed in water or olive oil.
You can use this sauce on pasta or rice, if you like. We usually like to eat it as a hot dip with bread, just like my late mother-n-law used to make.
