Course: Main Dish
Cuisine: Gluten-Free, Oil-Free Option, Vegan
Servings: 8 medium bowls

Ingredients

  • 1 1/2 cups white quinoa (uncooked)
  • 1 onion
  • 1 green bell pepper
  • 8 oz. sliced mushrooms
  • 3 roma tomatoes (or grape/cherry tomatoes)
  • 1 cup fresh spinach
  • 3 cloves garlic
  • 15 oz. can tomato sauce (or less to taste)
  • 1 cup vegan mozzarella shreds (Miyoko's, Follow Your Heart, etc.)
  • 1 tsp. dried basil
  • 1/2 tsp. dried oregano
  • Salt to taste

Instructions

  • Preheat oven to 375.
  • Cook quinoa: in a saucepan, add rinsed quinoa and 3 cups water (or veggie broth for more flavor). Bring to a boil, cover, reduce heat, and simmer for 15-20 minutes or until liquid is absorbed.
  • Meanwhile, chop onion, green pepper, and tomatoes. Mince garlic.
  • In a skillet over medium heat, saute onion, green pepper, and sliced mushrooms with salt for about 10 minutes or until softened. (I use 3 Tbsp. water/broth for no-oil saute method.)
  • Add garlic, stir, and saute 1 more minute.
  • When quinoa is cooked, place it in a large mixing bowl. Add tomato sauce, tomatoes, spinach, mozzarella, sauteed vegetables (any excess liquid removed), basil, and oregano. Stir to combine.
  • Spread mixture into a 9x13 inch baking dish (lightly sprayed if desired) and gently press down. Top with a light sprinkle of cheese if desired.
  • Bake for 20-25 minutes. Garnish with fresh basil if desired.

Notes

The recipe calls for a 15 oz. can of tomato sauce, but we only use about 10-12 oz. to our taste. I'd suggest starting with less and add more as you like. Or simply substitute 1-2 cups of your favorite marinara sauce for the tomato sauce, and tweak the seasonings from there.
Fresh basil makes a lovely garnish before serving!
