Instant Pot Mushroom Pasta

""This Instant Pot Mushroom Pasta is perfect for Meatless Mondays. It’s easy, inexpensive, filling, and delicious. That’s why it’s a staple on our dinner menu and one of my favorite Instant Pot recipes. Since I grind up the mushrooms, even my meat eating teenage boys find this dish satisfying. I guess since it looks more like a hamburger pasta dish, they don’t think of it as vegetarian, which is usually a term they associate with salads that don’t appease their voracious appetites.  ""
