2small apples or 1 large apple, thinly sliced into half moons
1/4cupolive oil, divided
1/2teaspoonbalsamic vinegar
sea salt, to taste
8slicesof bread of your choice
1 1/2cupsgrated cheese, I like to do a combination of white cheddar Monterey Jack, and gruyere
Instructions
Make the caramelized onions (can be done a day in advance).
Heat a large skillet over medium heat. Add in a heaping tablespoon of olive oil and the onions. Saute until onions are browned, about 8 minutes. Add in balsamic vinegar and continue to saute until onions are wilted and quite brown, an additional 5 or so minutes. Set aside.
Heat a medium sized nonstick skillet (or a large one if wanting to do all of them at once) over medium heat. Brush oil onto both sides of each bread and place on skillet. Toast until lightly browned and then flip.
Once flipped, add shredded cheese, caramelized onions, and apples onto one slice of bread. Place the other piece of bread on top. Repeat with other slices. Put a lid to cover pan for about 1-2 minutes melt the cheese on the inside without burning the bread. Once the cheese has melted, remove from pan and serve.
