Optional – herbs or spices.
I sprinkled some dried parsley, rosemary and thyme.
Preheat your oven to 350 degrees Fahrenheit.
Line a baking sheet with PARCHMENT paper (Do not try anything else)
I used Cracker Barrel Slices.
Cut sandwich slices into 4 equal sized pieces and place onto the parchment, a couple of inches apart.
I only placed 12 on a tray as they spread as they bake.
Bake ±7 minutes or until beginning to brown around the edges.
Leave them on the tray for ±5 minutes, to set a bit, before gently scooping it up with a plastic or metal egg-lifter and place on a cold surface or plate and allow to cool complete, to finish getting crispy.
Some additional info: Please note that as each oven differs, you may have to bake it a little bit longer to get it nice and crispy. Another factor would be the amount of fat/oil in your cheese. I ended up baking mine a bit longer (say in total about 10 minutes) but be careful not to burn them, to ensure it remains crisp. Today its still yummy and crispy like a chip.
Source: Saw this idea on the internet, and could not find the recipe again, so just winged it.
Made it from memory from way back then, so this will not resemble the original recipe in any way shape or form.
