TORTILLA CASSEROLE WITH TURKEY

Steps:

• Prepare the Salsa de Tomatillo. In a heavy, 6-quart, nonreactive saucepan over medium-high heat, combine tomatillos, chiles, and water; bring to a boil. Reduce heat to low and simmer until the tomatillos are tender, about 10 to 12 minutes. Drain, reserving 1/2 to 1 cup of the cooking liquid. Working in batches, combine tomatillos, chiles, reserved cooking liquid, garlic, and cilantro in a blender and blend to a smooth puree. In a heavy, 12-inch, deep-sided skillet, heat the oil over medium heat and cook the tomatillo mixture for about 10 minutes, stirring often. Add salt to taste.
• Prepare the casserole. In a heavy, 10-inch skillet, heat 3/4 cup of the corn oil over medium heat until the oil shimmers. Using tongs, submerge the tortillas, one at a time, in the hot oil for about 10 seconds (the tortillas should remain pliable). Transfer to a baking sheet lined with paper towels to drain. Lightly oil a 13-by-9-inch baking dish and set aside. In a heavy, 12-inch, nonstick skillet, heat the remaining 1 tablespoon of oil over medium heat until shimmering. Add both kinds of squash and cook over medium heat about 5 minutes. Add the corn and green beans and cook until just tender, about 2 to 3 minutes. Add salt and pepper to taste.
• Preheat oven to 375 degrees. Arrange 6 of the softened tortillas in the prepared baking dish, overlapping the edges. Cover with half of the shredded turkey, half of the vegetable mixture, 1 cup of the cheese, 1 cup of the Salsa de Tomatillo, and 3/4 cup of the sour cream. Repeat the layering process with 6 additional tortillas, the remaining turkey, vegetable mixture, and cheese, 1 cup of the Salsa de Tomatillo, and 3/4 cup of the sour cream. Top with the remaining 6 tortillas. Drizzle with 1 cup of the Salsa de Tomatillo, cover with foil, and bake in preheated oven for about 50 minutes, or until heated through.
• During the last few minutes of the cooking time, heat the remaining 3 cups Salsa de Tomatillo over low heat and keep warm. In a small bowl, whisk together the remaining 1/2 cup sour cream and the milk; drizzle over the hot casserole when it comes out of the oven. Serve the hot casserole with hot Salsa de Tomatillo on the side.
