Turkey Chili Verde

2 fresh poblano chiles
2 tablespoons canola oil
1 large onion, chopped
2 garlic cloves, minced
11â„4 pounds ground turkey, preferably a mix of white and dark meat
One 4-ounce can chopped mild green chiles
Two 11-ounce cans tomatillos, drained and chopped, or 12 fresh tomatillos, chopped
1 tablespoon ground cumin
11â„2 tablespoons chopped oregano leaves or
2 teaspoons dried oregano
1â„2 teaspoon freshly ground black pepper
4 cups (1 quart) chicken broth
3 cups canned white beans, drained and rinsed
1â„2 cup chopped cilantro leaves
2 tablespoons lime juice

Either toast the poblano chiles over an open gas fl ame by holding them a few inches above the fi re with metal tongs, turning them until theyâ€™re completely blackened; or broil them 4 inches from a preheated broiler on a lipped baking sheet or broiler tray, turning occasionally, until blackened on all sides. Place the chiles in a paper bag and seal well, or place them in a medium bowl and cover tightly with plastic wrap. Set aside for 10 minutes. Peel off the outer charred layer before seeding and chopping the chiles; set aside.
Heat a large saucepan or medium pot over medium heat, swirl in the canola oil, and add the onion. Cook, stirring often, until softened, about 3 minutes. Add the garlic and cook for 20 seconds.
Crumble in the turkey and cook, stirring frequently, until it loses its raw, pink color and browns somewhat, about 5 minutes. Add the canned chiles and the chopped poblanos; cook, stirring constantly, for 1 minute.
Add the tomatillos, cumin, oregano, and pepper. Stir well, then cook undisturbed for 30 seconds. Stir in the broth and beans and bring the mixture to a simmer.
Reduce the heat to low and simmer very slowly, uncovered and at the merest bubble, for 11â„2 hours, stirring occasionally.
Stir in the cilantro and lime juice, cover, and remove the pot from the heat to steep for 5 minutes before serving.
