Creamy Shrimp and Mushroom Pasta - This. was. so. delicious. Even as a leftover. We also added onions to the pan before the mushrooms, timing them so that they were caramelized as the mushrooms were finished. Subbed white pepper for red pepper flakes, and asiago for mozzarella. Next time, we'll cut the shrimp in half so that more bites have them. We put it on top of roasted spaghetti squash.
