I started sort of throwing this together a couple of years ago, I make this for company because everyone always carries on so about it. Recently, a friend needed a hand in providing a dish to pass for a pot luck at her church. I made this for her to take and I must say, it was the most popular thing there. We were asked to write out our recipes for people to share, so I thought the time had come to list it here as well. It's a very forgiving recipe so feel free to substitute to your hearts content. I would however, really recommend using the Swiss cheese--it's very good.
