Instructions
Preheat oven to 375°F (190°C).
Rinse 1 cup white quinoa under cold water. In a saucepan combine the rinsed quinoa and 1.5 cups water; bring to a light boil, then cover, reduce heat to low, and simmer 15–20 minutes or until the liquid is absorbed. Remove from heat, keep covered 5 minutes, then fluff with a fork.
While the quinoa cooks, prepare the vegetables: dice 1 yellow onion, 1 green bell pepper, and 8 oz. mushrooms; mince 4 cloves garlic; chop 1 cup fresh baby spinach; dice 3 roma tomatoes; chop 2 Tbsp fresh basil and set aside for serving.
Heat a large skillet over medium-high. Add the diced onion, bell pepper, and mushrooms. If you prefer a no‑oil sauté, add about 3 Tbsp water or broth to the skillet to prevent sticking. Sauté 7–8 minutes, stirring occasionally, until the vegetables are softened.
Add the minced garlic, chopped spinach, and 2 tsp Italian seasoning to the skillet. Stir and sauté 1–2 minutes, until the garlic is fragrant and the spinach has wilted. Turn off the heat.
In a large mixing bowl combine the cooked quinoa, the sautéed vegetables, the 15 oz. can tomato sauce, the diced roma tomatoes, and 3/4 cup vegan mozzarella shreds. (If you want some cheese visible on top, reserve a small portion of the 3/4 cup before stirring and set it aside for sprinkling.)
Spread the mixture evenly into a 9x13-inch baking dish and gently press down. If you reserved any cheese, sprinkle it over the top now.
Bake for 25 minutes. Remove from the oven and let the casserole rest 5–10 minutes to set.
Garnish with the chopped 2 Tbsp fresh basil before serving.

*Oil-free option:
Omit vegan cheese shreds. Substitute with up to 1/4 cup nutritional yeast for cheesy flavor if desired. You'll also want to add salt to taste to enhance the flavors.
