CHICKEN ENCHILADAS WITH SALSA VERDE

Steps:

• Prepare the chicken: Place chicken parts in a large saucepan with onion, garlic and salt, and cover with water. Heat pan over high heat until liquid comes to a boil, then reduce heat to medium and let simmer until chicken is cooked through, about 20 to 25 minutes. Remove chicken and let cool, reserving stock for another use. Using your fingers or two forks, shred meat from chicken and reserve, discarding skin and bones. (Alternatively, shred meat from leftover or store-bought roast chicken and set aside.)
• Meanwhile, heat oven to 375, and make the salsa verde: Combine tomatillos, onion, garlic, serranos and cilantro in a blender or food processor and purée until smooth, adding water as needed to thin it out a little. Season with salt to taste.
• Prepare the tortillas: In medium sauté pan set over medium-high heat, heat oil until it begins to shimmer. Using tongs or a wide spatula, place a tortilla in the hot fat; it should start to bubble immediately. Heat tortilla for about 10 seconds a side, until soft and lightly browned. Remove tortilla and set on a rack set over a baking pan, or just on a baking pan if you don't have a rack. Repeat with remaining tortillas, working quickly.
• Assemble the enchiladas: Use a ladle to put about 1/2 cup salsa verde in the bottom of a 9-by-13-inch baking pan and spread it out a little. Roll a few tablespoons of shredded chicken into each tortilla with a teaspoon or so of salsa verde and place it seam-side down in the pan, nestling each one against the last. Ladle salsa verde over top of rolled tortillas and sprinkle with about half the crumbled cheese.
• Transfer to oven and bake until sauce bubbles and cheese is melted, about 15 minutes. Dot with crema, sprinkle with remaining cheese and, if using, chopped onion, then serve immediately.
