Make the Cheddar Cheese - click here or directions.
Roast the Shiitake Mushrooms - click here for directions.
Spread cheddar cheese on one slice of bread per 2 for a sandwich. Toast bread until lightly browned and cheese has warmed. While bread is toasting prepare sauce - mix 2 tablespoons of Veganaise with 1 - 2 teaspoons of Truff Hot Sauce (make it as spicy as you want!).
Assemble layering with Shiitake, tomato, lettuce and sauce. Season with a few grinds of fresh pepper. Cover with top piece of bread. Slice and serve immediately.
Notes
I used straight hot sauce in my original recipe photo, but you can lighten it up by mixing with vegan mayonnaise.
