GRILLED CHEESE WITH BALSAMIC GLAZED MUSHROOMS, ONIONS, AND FRESH SPINACH
Makes 4 sandwiches prep time: 10 minutes cooking time: 30 minutes
2 Tbsp salted butter
2 cups crimini mushrooms, sliced
1 sweet onion, sliced
2 Tbsp balsamic vinegar
8 slices bread
2 Tbsp butter, room temperature
4 slices American cheese
1 cup baby spinach
In a large frying pan, heat 2 Tbsp butter on medium heat. Add the sliced mushrooms and onions and fry until translucent, approximately 5 minutes. Add the balsamic vinegar and continue to fry until the mushrooms and onions have formed a nice dark caramelized glaze, approximately 20 minutes.
Heat a large frying pan on medium.
To assemble the sandwiches, butter the bread, one side only. With the buttered side on the outside, fill each sandwich with a slice of cheese and a quarter of the onion/mushrooms mixture. Place the sandwiches onto the frying pan (as many as will fit into the pan at once) and cover with a tight fitting lid. Fry each side until golden brown, and the cheese is melted.
Remove from the pan and add 1/4 cup of baby spinach to each sandwich. Slice in half and serve warm.
