Grown-Up Grilled Cheese

All you need is two thick slices of hand-cut bread, a tablespoon of softened butter and the filling combo of your choice. Spread butter on one side of both slices of bread, lay the bread on a work surface, butter-side down, and put the fillings inside. Place sandwich in an already hot nonstick pan (or several, if you are making more sandwiches) on medium heat. Cook 5 minutes, flip, then cook 2 more minutes. Cut sandwich in half and serve immediately.
