Pre-heat oven to 350 degrees. Chop peppers, onions and garlic, then set aside. In a medium pot, add 1 tbsp olive oil over medium heat. As the oil begins to heat, add the garlic and stir for a minute. Add the tomato sauce and chipotle pepper, 2 tsp of Adobo sauce and stir. Let simmer over low heat for about 5 minutes, occasionally stirring, then remove from heat. While this is simmering, heat the Del Real Foods® Chipotle Chicken Tinga according to the directions on the package. In a medium skillet over medium heat, sauté the peppers and onions in the remaining 1 tbsp of olive oil, until they begin to soften, then remove from heat. Coat an 8×11.5′′pan with cooking spray. Lightly coat the bottom of your baking pan with about 2 tbsp of the tomato sauce. Remove the husk from 3 tamales and cut into slices, then arrange them at the bottom of the pan. Add the Del Real Foods® Chipotle Chicken Tinga over the tamale slices and spread evenly. Sprinkle 1/3 cup shredded cheddar over the chicken, then add 1⁄2 of the peppers and onions. Cut the remaining 3 tamales into slices and arrange over the top of the chicken. Add the remaining peppers and onions, then evenly pour the tomato sauce over the top. Top with remaining shredded cheese. Bake for 20-25 minutes. Allow to stand for up to 5 minutes before serving.
