Irresistible Green Pozole

Name: Irresistible Green Pozole
Ingredients: two 15 ounce cans cooked hominy, or 4 cups home-cooked hominy (8 ounces dry will yield approximately 4 cups); 1 large white onion, sliced thin lengthwise; 6 cloves garlic, peeled and chopped; bay leaf; salt; 3 pounds skinless boneless chicken thighs (I'm sure you could also use breast meat, but I don't think the resulting broth would be as flavorful); 1/2 cup pepitas; 1 pound tomatillos, husks removed and rinsed with warm water; 1 -2 bunches fresh cilantro; 1 teaspoon dried epazote or dried oregano; 2 tablespoons canola oil
