Dice the poblano chiles and throw them into the pot with the onions & jalapeño if you don’t feel like roasting them! This is a good option if you’re short on time.
Meanwhile, place the tomatillos in a food processor, and process until smooth. Set aside. Add garlic and cumin to the pot; sauté 1 minute, stirring constantly.
Cover, reduce heat, and simmer for 10 minutes or until vegetables are tender. Add roasted poblanos and hominy; cook for 2 minutes or until heated through.
