Remember that shepherd’s pie topped with roasted garlic cream cheese mashed potatoes I made last week? It was so good that Mike and I almost inhaled the entire pan in one sitting. As we were eating, I was getting a little worried that we wouldn’t have any leftovers. See, I’m a huge fan of leftovers – especially when you take them and turn them into something else. Something else like this insane shepherd’s pie grilled cheese. Yup, I literally put a piece of shepherd’s pie between two(!) grilled cheese sandwiches to make a crazy, carbo-licious sandwich monstrosity.
