Ok, grilled cheese is one of those comfort foods that despite my best efforts to make healthy, I fail. Always looking for more decadent cheeses, more flavor combinations to add in and just more of the gooey awesomeness that is melted cheese. This time I had some leftover gruyere that I knew would be perfect with turkey. It needed some balance and tomatoes provide just the right acid to cut through the rich cheese. The result? Amazing. Seriously, it was very good and so simple. By lightly brushing the bread with olive oil before grilling instead of using butter, it makes this as healthy as grilled cheese can be modified to be when using decadent cheeses.
