Israelis apparently call chicken thighs 'triangles'.
This is so even if the fillet piece is not separated from the bone piece.
Recipes for triangles include some where you wrap the chicken thigh and spices in foil and some (see image) where you take the fillet out of the thigh and cook it separately and some where you make a triangle out of basically a thick chicken stew covered with dough.
We had chicken triangles when my daughter (from Israel) was visiting us.
