Cook macaroni pasta on the stovetop according to package instructions.
Saute sliced cremini mushrooms in olive oil over medium heat for 8-10 minutes (until mushrooms are dark in colour and all the moisture has evaporated).
Combine ingredients for the sauce in a high-speed blender and blend until smooth.
In a medium bowl mix together cooked pasta, spinach sauce, chopped jalapenos, mushrooms and daiya cheese. Stir until well combined and then spoon into a small baking dish.
Garnish with extra cheese and bake uncovered at 350 for approx. 20 min.
