Cooking teacher and dearest friend Ann Amendolara Nurse serves these wonderful tarts as an appetizer for a light meal. They are absolutely addictive—try them in a smaller size, too, as an hors d’oeuvre.
To make the filling, heat the olive oil in a heavy sauté pan over a medium flame. Add the scallions and cook slowly until they are limp, about 10 minutes. Drain the scallions in a strainer or colander for 5 minutes. Transfer the scallions to a bowl and gently stir in the remaining filling ingredients.
