In a large skillet warm the oil over medium heat. Add the onion and cook for 2-3 minutes, until translucent. Add the bell pepper, minced garlic, 2 teaspoons chili powder, 2 teaspoons cumin, and 1 teaspoon oregano. Stir to combine and continue to cook for about 5 more minutes.
To the skillet, add the drained and rinsed beans, rinsed quinoa, tomato sauce, salt, and 1⅓ cup water. Stir together then turn the heat to medium high and bring to a low boil. Cover with a lid and allow to cook for about 20-25 minutes, stirring intermittently.
When its finished the quinoa will be soft and most of the liquid will have absorbed. Serve the quinoa warm with avocado or guacamole, fresh cilantro and tortilla chips. Leftovers can be stored in an airtight container and refrigerated for up to 5 days.
