Pumpkin Pasta with Mushroom & Kale

Bring 4 cups water to a boil in pot, add pasta, and cook for about 7-10 minutes (according to package instructions), adding kale during the last 30 seconds. Reserve 2 Tbsp water, drain, return to pan, and cover to keep warm.
Heat oil in a large skillet on medium-high heat and fry the onions and garlic for about 2 minutes until translucent. Set aside half the mixture.
Add mushrooms to skillet and cook until they begin to brown, about 4 minutes.
Blend reserved onion-garlic mix and sauce ingredients in a food processor or blender, until creamy and smooth, about 15 sec.
Add sauce, pasta and kale to skillet with mushrooms, toss to combine, and serve immediately!
Optional: Bake in a 350°F oven for 15 minutes until top gets crispy.
