Cheesy Caprese Quinoa Casserole

Directions

1. 1
   To a medium saucepan, add quinoa and 2 cups water. Bring to a boil and then turn down to medium-low to simmer for 10-15 minutes until quinoa kernels have "popped."
2. 2
   Transfer to another bowl. In the same pan, add cooking oil and saute onion until soft.
3. 3
   Add crushed tomatoes (or pasta sauce), balsamic vinegar, salt, pepper, and 2 tablespoons of fresh basil. Simmer on medium-low for 10-15 minutes.
4. 4
   Add quinoa to sauce, along with half of the mozzarella cheese.
5. 5
   Transfer into a greased 8x8 inch baking dish and top with remaining 1/2 cup mozzarella cheese, 1/4 cup parmesan cheese, and tomatoes.
6. 6
   Bake at 400 degrees for 15 minutes, and then turn the broiler on for the last 60 seconds or so to just slightly toast the cheese.
