I love, love, love these sandwiches! I have been making this for years and my children love them also. I make these to take to pot lucks as well and there is never any left. I got this from an old Good House Keeping book that has since fallen apart and I wanted to add it to a new cookbook I am doing so my children will have it. I tweaked the original by making these into little sandwiches and not open faced and by adding regular yellow onions instead of green onion but try the green onion if you prefer. I liked the yellow onion better. You can half this recipe. Enjoy!
