Caramelized Onions:

- Cook onions until soft, about 10 minutes, add in salt and sugar(optional) to help caramelization.
- Continue cooking on medium low heat until onions are dark brown. This will take 20-30 minutes, stir and scrape the pan occasionally while it cooks down. Once onions are dark brown add a splash of balsamic vinegar to deglaze the pan.
Sandwich Assembly:
- Sauté mushrooms in a pan of heated olive oil for about 5 minutes until soft and browned. Add a pinch of salt and pepper to season. Set aside.
- Grate your cheddar and Parmesan cheese.
- To assemble sandwich, butter both slices of bread on outer side. On interior of one slice spread a thin layer of Dijon mustard. Top with half the caramelized onions, mushrooms, cheddar cheese, Parmesan cheese, and a sprinkle of black pepper. Top with other slice of bread.
- In a pan heat up a drizzle of olive oil or 1 teaspoon butter on medium heat. Once heated put in sandwich. Cook on each side for 2-3 minutes or until golden brown and cheese is melting. Once cheese is thoroughly melting remove from heat.
- Serve immediately.
- Enjoy!
