Cheese and fruit are a classic pair, so why not enjoy them in a sandwich? In this updated version of grilled cheese, we’ve used delicious, antioxidant-rich frozen raspberries to make a tart jam that... turns a simple grilled cheese sandwich into a gourmet treat. Fruit is so good for us, and this is a creative way to get more of it.
In a small pot combine frozen raspberries, balsamic vinegar, thyme, and honey. Cover with a lid and simmer over medium heat for 10 minutes. Uncover and continue to simmer until reduced and jammy. Turn off the heat.
Lay down 2 slices of bread on a board, spread the raspberry jam evenly, top each slice with a layer of cheese, then top with the remaining slices of bread. Press lightly. Butter both sides of the sandwich.
Heat a cast-iron skillet or griddle over medium-low heat. Place the sandwiches in the pan, and cook until golden brown on each side and the cheese has melted, about 3 to 4 minutes per side.
