My husband and I used to make these all the time about 40 years ago when my kids were little. And I haven't made them since... until yesterday! I kept seeing the recipe in my cookbook and finally decided to try them again. They were absolutely delicious. And my now grown daughter husband and two granddaughters absolutely loved them and they are so easy to make!! I had written down a hint for them to butter the buns and let them broil just until starting to get brown and then put the mixture and cheese on top and freeze them. And I will always do it that way now.
