I cannot credit the original recipe source for this recipe as it has been lost in the depths of time. Every time I make these I do thank that original recipe developer. These freeze well, so make a double batch and keep them in the freezer for emergencies. They work well both as canapes or tucked into children's lunchboxes. To make these vegetarian, substitute semi-dreid tomatoes for the ham. You will need shallow patty pan trays to make these quiches.
