  • 1 cup dry quinoa
  • 3 cups vegetable broth
  • 1 can (15 ounces) diced fire roasted tomatoes
  • 10 ounces red enchilada sauce
  • 4 ounces diced green chiles
  • 1 cup sweet corn frozen or canned
  • 2 cups black beans (about 1.5 cans)
  • 2 cups Mexican blend shredded cheese divided in half
  • 1 teaspoon cumin
  • 1 teaspoon chili powder
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon salt
  • optional toppings: avocado or guacamole, salsa, diced jalapeno, cilantro, lime


  • Preheat the oven to 350 degrees F.
  • Rinse quinoa in a fine mesh sieve under running water for at least 30 seconds. This removes any bitterness that the quinoa might have.
  • Combine the rinsed quinoa and vegetable broth in a medium saucepan. Bring to a boil over medium-high heat. Reduce to a simmer over medium-low heat and cover with a lid. Simmer for 15-20 minutes, or until quinoa is cooked through.
  • Combine all ingredients, except for 1 cup of cheese, in a large mixing bowl. Stir to combine.
  • Add mixture to a two quart baking dish. Sprinkle with reserved cheese.
  • Bake for 20 minutes at 350 degrees, or until cheese is melted and turning golden.
  • Remove from oven and let cool for 5 minutes before serving. Serve topped with avocado or guacamole, fresh cilantro and salsa.


  • Mexican blend cheese: Usually includes sharp cheddar, colby jack and Monterry jack. Any of these three cheese can be used in place of a cheese blend.
  • Keeps for 3-4 days in the fridge.
  • Freeze for later: Let thaw completely. Transfer individual portions into freezer safe containers. Freeze for up to 3 months. Let thaw completely in the fridge before reheating.
