Step 1

Remove all the stems from the mushrooms and add them to a food processor fitted with the blade attachment. Add half of the mushroom caps, slightly breaking them up with your hands as you add them. Pulse the mushrooms until they are finely chopped. Set aside. Halve and slice the remaining mushroom caps and set aside.

Step 2

Heat a large Dutch oven over medium-high heat. Add the oil and heat until shimmering. Add the finely chopped mushrooms from the food processor and 1/2 teaspoon salt. Cook until the natural liquid from the mushrooms has released and evaporated, about 4 minutes. Add the cilantro stems, celery, bell peppers, onion, poblano pepper and 1/2 teaspoon salt. Cook, stirring occasionally, until the vegetables begin to soften, 4 to 5 minutes. Add the chili powder, smoked paprika, cumin, coriander and garlic. Stir to coat until the spices are fragrant, about 1 minute. Add the crushed tomatoes, diced tomatoes, zucchini and sliced mushrooms. Stir to combine. Bring the mixture up to a boil, then turn the heat down to low. Cover and simmer for 30 minutes.

Step 3

Remove the lid from the Dutch oven and add the corn, black beans and pinto beans. Stir to combine. Continue cooking until the corn and beans are heated through, an additional 5 minutes. Season with salt.

Step 4

Ladle the chili into bowls and top with the desired toppings.
