This was my Grandmothers' recipe. We always had it on Sunday with her famous stuffed meatloaf ;) It is especially wonderful as a side dish on a hot summer afternoon. I think this and her butterscotch pie bring back a smile or dozen for me. I hope you enjoy it!!
Whisk together mayonnaise,canned milk(or cream-it's up to you),apple cider vinegar,granulated sugar(use the lesser amount and add from their to suit your personal taste).
Then add the pepper and salt(you can use regular salt).Put your lettuce in a bowl and add the slivered onion..pour the mayo mixture over the lettuce and then fold in the egg. Make sure you mix it so all is blended.
