Next, toss in the bell pepper, zucchini, and mushrooms. Saut for another 5-7 minutes until they are tender, then add the cherry tomatoes and spinach until wilted, and remove from heat.
Make the Sauce: In a separate bowl, combine the tomato sauce and Greek yogurt, stirring until creamy. For an added kick, sprinkle in the optional red pepper flakes.
Assemble Casserole: Preheat your oven to 190 °C (375 °F). In a large bowl, mix the fluffed quinoa with the saut ed veggies and the creamy sauce. Transfer this mixture to a greased 9 13-inch baking dish, spreading it evenly.
