Kitchen tip

• We love using two kinds of beans because it gives the chili a nice mix of texture and flavor. Every bite feels hearty and satisfying without needing any meat at all.
• Try toasting your spices before adding the liquids. It takes just a minute, but that quick sizzle brings out such a deep, smoky flavor that makes the chili taste like it's been slow cooked for hours.
• Don't skip the tomato paste because it's the secret to that rich, thick sauce that clings to every spoonful.
• If you like your chili thicker (like we do), add the quinoa halfway through cooking. It soaks up just enough liquid to make the chili perfectly hearty without turning mushy.
