French Onion Soup in a Sandwich

Do you like french onion soup? Do you like sandwiches? Well hot damn, put caramelized onions into your grilled cheese then! This can be done with any cheese you like, but I prefer muenster or gruyere. Today I used muenster and Challah bread.

For this you will need:

Two reasonably thick slices of Challah bread
Two slices of muenster cheese
A good amount of butter
One Vidalia onion
One tbsp white balsamic vinegar
Olive Oil
Salt

First, slice the onion and add to a pan with olive oil on medium heat. Add salt and stir.

After they have started to brown slightly, turn the heat to low and let caramelize for approximately 20 minutes, stirring occasionally. Once they look like the below, add white balsamic vinegar and scrape up brown bits at the bottom of the pan.

Let the onions cool and begin to assemble your sandwich. Place one slice of cheese on each piece of bread, then gently place the caramelized onions between. Melt a tablespoon or two of butter in a pan on medium heat and place sandwich in pan.

 

After a minute or two, set the heat to low and flip. Then cover with a lid to ensure the cheese melts.

Slice and try not to inhale the whole thing at once!
