This is a quick, easy one-pot recipe. Great for a healthy weeknight meal that will leave you enough to bring leftovers to work.
Heat oil in heavy medium saucepan over medium-high heat. Add onions and red pepper (and garlic); sauté until beginning to soften, about 5 minutes. Stir in next 4 ingredients (plus cayenne). Add water; bring to boil. Cover, reduce heat to medium-low, and simmer until quinoa is almost tender, about 14 minutes. Add beans and 1/4 cup cilantro; cook uncovered until heated through and liquid is fully absorbed, about 3 minutes. Transfer to bowl; sprinkle with 1/4 cup cilantro and cheese, if desired
I served it with some guacamole I whipped up. You can also just throw some avocado chunks into your bowl for garnish.
