Prepare the Green Sauce: In a blender, combine the tomatillos, cilantro, parsley, and a bit of the vegetable broth to facilitate blending. Process until smooth.
Cook the Vegetables: Heat the olive oil in a large pot over medium heat. Add the onions, garlic, poblano peppers, and jalapeños. Cook, stirring frequently, until the vegetables are softened, about 5 minutes.
Combine Ingredients: Pour the green sauce into the pot with the cooked vegetables. Add the remaining vegetable broth, hominy, cumin, and oregano. Season with salt and pepper.
Simmer the Pozole: Bring the mixture to a boil, then reduce the heat to low and let it simmer for about 30 minutes to allow the flavors to meld together.
Adjust Seasonings: Taste the pozole and adjust the seasoning with additional salt, pepper, or spices as needed.
Serve: Ladle the pozole into bowls and let each person customize their toppings with radishes, cabbage, avocado, lime wedges, tortilla strips, and extra cilantro.
