Sourdough Jack
The Frisco Breakfast Melt was a Hardees offering in the 90s. One of the reasons I was a fatty. They were that good.hardees had one called a frisco melt that sounds like that. this was in 2004 - 8 though when i lived near one.
I came in here thinking the OP just crapped out a burger he ate in the mid 90's. What a relief. Your butt probably would have whistled some Ace of Base as it came out.
Thompson also played a role in developing some of the chain's new products, including the recently introduced Parmesan Sourdough Burger and the Chicken Sourdough Italiano sandwich.
