caramelized onion, havarti + mozzarella grilled cheese

Delicious, I will definitely make it again. I added some balsamic vinegar as someone else suggested it went great with the onions

Oh so gooey decadent yumminess! The caramelized onions and mild cheese really complemented the tomato basil soup I made tonight. I couldn’t find sliced havarti, so we used Muenster along with the mozzarella. I also deglazed the caramelized onions with balsamic vinegar. I recommend a slow cook over medium-low to medium heat for grilling these sandwiches so the cheese melts through and the crust gets golden brown but not burnt.
