  • 4 small bell peppers , halved and seeded
  • 1/2 cup uncooked quinoa
  • 3 tbsp olive oil , divided
  • 1 lb (450g) cremini mushrooms , finely chopped
  • 1 onion , chopped
  • 2 cloves garlic , minced
  • 1 14.5 oz can (450g) diced tomatoes
  • 1 tbsp fresh thyme , leaves only
  • 3/4 tsp salt
  • 1/2 tsp black pepper
  • 1/2 cup shredded parmesan cheese
  • 1/4 cup toasted slivered almonds
  • 1/4 cup chopped fresh parsley
  • lemon juice from 1/2 lemon
  • 1 cup shredded mozzarella cheese


  • Cook quinoa according to package instructions.
  • In a large skillet, over medium heat, heat 2 tablespoons of olive oil. Add the mushrooms and onion, and cook, stirring, until softened and all the moisture has disappeared (about 10 minutes).
  • Add the garlic and cook for 30 seconds. Stir in the canned tomatoes, thyme, salt, and black pepper. Simmer over low heat for about 10 minutes more.
  • Turn off the heat and stir in the cooked quinoa, Parmesan cheese, almonds, and parsley.
  • Preheat the oven to 400°F (200°C).
  • Place the pepper halves, cut sides up, in a large baking dish. Spoon the mushroom quinoa mixture into the peppers, mounding if necessary. Drizzle with the remaining tablespoon olive oil and lemon juice.
  • Cover with foil and bake for about 50 minutes - 1 hour, or until the peppers reach your desired level of tenderness.
  • Uncover, top with the shredded mozzarella cheese, and bake for 5-10 minutes more until the cheese has melted.
