  • Add olive oil to a hot pan. Add sliced onion and cook on medium heat for about 35-40 minutes, or until onions are caramelized. Add balsamic vinegar to deglaze the pan.
  • Add sliced mushroom and tamari, and cook until mushrooms are tender.
  • Place vegan Swiss cheese on bread. Broil or toast 3-5 minutes, until cheese is melted*.
  • Spoon caramelized onions and mushrooms on top of vegan Swiss.


You could also assemble sandwiches and cook them in a pan on medium high heat on both sides until the bread is golden brown. I prefer broiling the vegan cheese first, and then making the sandwiches because that way it is a little less messy.
