Cook raw quinoa in 2 cups water according to package directions. Let cool.: You will notice the water bubble gently as the tiny grains swell and begin to separate, releasing a faint nutty aroma. When properly cooked the quinoa looks translucent with a visible white spiral. Fluff it with a fork and spread it on a plate briefly so steam escapes and it cools, this prevents clumping when added later. If quinoa is gummy, it was likely over stirred or cooked with too high a heat, so next time reduce heat to maintain a gentle simmer.
Add vegetable oil, uncooked ground beef, diced white onion, and minced garlic to a large stock pot. Heat pot on medium-high heat until beef is brown and cooked. Drain any excess grease.: As the vegetable oil warms you'll smell a faint clean scent before the onion softens and becomes glossy. The lean ground beef should sizzle and then brown, producing savory browned bits at the bottom of the pot that lift flavor. The garlic becomes fragrant quickly, so add it when the onion is soft to avoid burning. When the beef shows no pink, use a slotted spoon to transfer to a paper towel lined bowl or drain the fat, excess grease can weigh the chili down.
Add minced garlic, chili powder, ground cumin, dried oregano, kosher salt, and black pepper and mix well.: Right after the fat is drained, the kitchen will fill with warm spice notes as the chili powder and ground cumin toast briefly in the residual heat, releasing brighter aromas. Stirring helps the spices coat the meat and onion so each bite has balanced seasoning. The oregano and pepper add herbal and peppery accents. A common mistake is adding too much salt at once, so I recommend tasting later once liquids are added.
Stir in COOKED quinoa, can of undrained green chilies, can of tomatoes, black beans, cannellini beans, can of drained corn, chopped green bell pepper, and beef broth.: When these wet and dry components meet you will hear a comforting simmer begin as the pot fills. The crushed tomatoes lend body and acidity, while the canned green chilies and corn add little textural pops. Folding in the cooled quinoa ensures it does not break down into mush. Keep everything moving so it blends evenly, and scrape the bottom to incorporate any browned bits. Avoid dumping in everything too fast which can make splatter or stop a gentle simmer.
Heat on medium high, covered, stirring occasionally until boiling.: You will see steam and hear the pot build intensity as the surface moves to a steady boil, with larger bubbles breaking at the top. This vigorous heat helps meld the flavors quickly, but watch for boil overs, and stir to keep ingredients from clinging to the base. If the chili begins to stick, reduce heat slightly; a scalded bottom can impart a bitter note to the pot.
Reduce heat to simmer and heat, covered, for 20 minutes or until bell peppers are soft and tender.: At a simmer the surface will show gentle bubbles and a soft whisper of steam. This slow finish lets flavors marry and allows the green bell pepper to become tender while keeping some texture. You will notice the sauce thicken and the aroma deepen, indicating the ingredients have harmonized. A common error is simmering too briefly, which leaves raw pepper crunch and a discordant texture.
Serve bowl of quinoa chili with fresh chopped cilantro and a variety of extra chili toppings (suggestions listed below).: When ladled into bowls the chili should be hot enough to release steam, and the garnish of chopped cilantro will add a fresh, herbaceous hit against the warm spices. Offer toppings at the table so each person can customize. Be careful with hot bowls, and stir before serving to reincorporate any settled juices.
