OMG...I had these frozen pretzels in my freezer, the typical ones you find in your grocer's frozen aisle. I felt these needed a better plan than the whole just "dipping into mustard" scenario.
I let the pretzels thaw out and sliced them in half with my bread knife. I precooked my bacon in the oven and layered it on the bottom half of the pretzel slices. I topped the bacon with Havarti cheese slices, but you can choose any kind of cheese you like. Then popped them in a nonstick skillet with a little butter to melt the cheese and warm the bacon through.
Simple and exquisite. And no one will complain when you pull out a tray of these.
