Rinse the quinoa under cold water in a fine-mesh strainer, then combine with 1 cup water in a small pot. Bring to a boil, then reduce heat and simmer for 15 minutes until the water is absorbed and quinoa is fluffy. While the quinoa cooks, prepare all your vegetables: dice the onion into 1/4-inch pieces, mince the garlic, seed and finely chop the jalapeño, dice the carrot and celery into 1/2-inch pieces, dice both bell peppers, and cut the zucchini into 1/2-inch chunks. This advance prep means everything will cook smoothly without scrambling when the pot gets hot.

Heat the olive oil in a large pot over medium heat. Add the diced onion and cook for 5 minutes until softened and translucent. Then add the minced garlic and jalapeño, stirring constantly for about 30 seconds until fragrant. Add the carrot, celery, both bell peppers, and zucchini, cooking for 10 minutes, stirring occasionally until the vegetables begin to soften and release their flavors. This layering technique—starting with onion, then adding garlic and heat-sensitive jalapeño, then the harder vegetables—ensures everything cooks evenly and develops proper depth of flavor.

Add the drained and rinsed black beans and red kidney beans to the pot, followed by the diced tomatoes and tomato sauce. Stir everything together, then add the cooked quinoa from Step 1. Sprinkle in the chili powder, ground cumin, and season generously with salt and black pepper to taste. I find that adding the spices at this stage allows them to bloom in the warm liquid and distribute evenly throughout the chili, rather than clumping up.

Reduce the heat to medium-low and simmer the chili for 30 minutes, stirring occasionally. This gentle simmering allows the flavors to meld together and the chili to thicken slightly. Taste and adjust seasonings if needed—adding more salt, pepper, or chili powder to suit your preference. The longer simmer time is crucial; I always say chili improves when you let it sit and develop, and you'll notice the flavors becoming richer and more cohesive by the end.

Ladle the chili into bowls and top with your choice of garnishes and accompaniments. The bright green onions add a nice crunch and freshness that cuts through the richness, while avocado slices provide creaminess and sour cream or Greek yogurt add tang. Serve with crackers or chips on the side for texture, and add cheese if you want extra richness.
