Equipment

  • 9 x 13 inch casserole dish

Ingredients

  • 6 large croissants cut in half
  • 1 cup fresh mushrooms sliced
  • 1 bunch green onions chopped
  • 6 large eggs beaten
  • 2 tbsp heavy whipping cream or whole milk
  • 2 tbsp butter
  • ½ cup chopped turkey or ham sandwich meat

  • ½ cup sharp cheddar cheese
  • ¼ cup Parmesan cheese

  • Slice your croissants in half.

  • Toast the croissants at 350 degrees for about five minutes or until just slightly browned.
  • Cover the croissants with Swiss cheese (be careful the pan may be hot from toasting).
  • Heat the butter in a large skillet and combine the mushrooms, sandwich meat, and green onions. Saute on medium for about five minutes and then set aside to cool slightly.
