"I made this dip on 12/2/16! I took it to our Social Hour at my retirement community and everyone really enjoyed it-it was practically gone! I omitted the parsley and instead of Swiss cheese, I'd used "Double Cheddar" shredded Cheddar cheese: 1-1/2 cups and a whole sweet chopped Vidalia onion! I kept the mayo and Parmesan cheese the same! I sampled what was left and I admit that it WAS very tasty! delowenstein"

"I made this YEARS ago when I was still a teenager for my family gatherings for holidays. Now I am requested to bring it to every gathering. The key to getting it to cook all the way through and brown nicely is to cook it in a nice shallow pan- maybe only 1-1 1/2 inch deep. Try it!"

"This is a keeper. I made this for an impromptu happy hour with friends and it was delicious. My husband even like it and he doesn't like manyonnaise or Parmensan cheese. I just didn't tell him what was in it! Will definitely make again. Served it with crackers and pita toast points."
