I'm trying to recreate the recipe and I can't remember what cheese they used...Gruyere maybe? I believe they used Black Forest Ham and Honey Mustard as well. They didn't sell them for long but they were deliciously addictive!
Have you hopped on the toaster oven dessert train yet? If not, now is the time and crostatas are the reason. Tapping into the power of your toaster oven (for more than just reheating pizza) is a real pro move when you're oven is fully occupied.
