Make yellow squash into “noodles” using a vegetable spiralizer (Optional: spread out to dry out on a paper towel before proceeding.) Sauté noodles on medium heat in a frying pan with 1 tablespoons melted butter, stirring occasionally. Add red pepper flakes and cayenne. The noodles are done when they start to turn translucent, about 5 minutes. Taste a squash noodle strand to make sure they are the desired texture. Add cream cheese, cut in small chunks, and oregano. Stir occasionally until cream cheese is completely melted and hot. Salt and pepper to taste. Sauce will thicken a bit as it cools.
