In a medium saucepan, bring rinsed quinoa and 2 cups of water to a boil. Reduce heat and simmer until all the water is absorbed and quinoa is tender, about 20 minutes. Fluff well with a fork and set aside.
While quinoa is cooking, heat olive oil in a stockpot over medium-high heat. Saute onion, celery, bell pepper, and zucchini until slightly softened, about 5-7 minutes.
Add garlic and saute until fragrant, or about another 30 seconds.
Add jalapeno pepper (and seeds), chili powder, salt, ground cumin, smoked paprika, dried oregano, ground black pepper, crushed tomatoes, and vegetable broth. Simmer, covered, for 15 minutes.
Add kidney beans, black beans, and corn and simmer, still covered, for another 5 minutes.
Add cooked quinoa and immediately remove from heat.

Notes
To prevent quinoa from clumping, it is extremely important to thoroughly fluff the quinoa with a fork immediately after cooking.
~1.5 cups of frozen corn can be substituted for the canned, if desired.
To make less spicy, add less than half of the jalapeno seeds. To make more spicy, add more than half of the seeds.
