Marinate mushrooms, roast in the oven at 400 degrees for 15 minutes. Do the same for sliced onions and cilantro. It is easier to roast separately.Once the mushrooms are roasted, slice them and mix them with the onion and cilantro mixture. Keep warm in a steam table for service. Serve on warm tortillas with pineapple salsa and avocado crema.
Put all ingredients in a blender and mix together until very smooth.
Mix all together and serve chilled.
