Cashew Cheese:

  • Soak raw cashews for 2 hours to overnight in hot water in the fridge.
  • Drain cashews from water. Add to food processor. Process 1-2 minutes. Add cashew milk and salt. Puree until smooth. Set aside.

Peppers and onions:

  • Thinly slice onions. Add to a large skillet over medium heat that has been sprayed with non-stick (I used olive oil). Cook 2-3 minutes.
  • Add thinly sliced green bell peppers to onions. Saute 2-3 minutes. Add 1-2 tbs. water to pan and allow to cook over medium low heat until onions and peppers have softened just a bit. Add balsamic and aminos. Stir and cook 2 more minutes. Take off heat.Taste for salt and add black pepper to your liking.


  • While peppers and onions are cooking, slice mushrooms.
  • Add mushrooms to a large saute pan sprayed with non-stick spray. Alllow to cook 3-4 minutes without adding salt or liquid. After that time, add salt and thyme. Saute 2-3 minutes, allowing some of the moisture to come out of the mushrooms.
  • Add balsamic and aminos. cook 2 minutes.
  • Take off heat and taste for salt and add black pepper to taste
  • To assemble the sandwich, cut rolls through the center. Dig out any extra dough from the center.
  • Spread some cashew cheese one one side of the roll. Add mushrooms then top with green pepper and onions. Enjoy!
