Instructions
- Step 1: Preheat your oven to 190°C (375°F).

- Step 3: While the quinoa cooks, heat olive oil in a large skillet over medium heat. Sauté the diced onion and minced garlic until fragrant, about 2–3 minutes.

- Step 6: Transfer the mixture into a greased baking dish. Sprinkle shredded mozzarella cheese evenly over the top.
- Step 7: Cover the casserole with foil and bake for 20 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden.
