Preheat oven to 350°F. Grease a cast iron skillet with nonstick spray. Set aside.
In a large bowl, stir the refried beans, sour cream, green chilis, cream cheese, and taco seasoning until well mixed together. If you have one, an electric hand mixer works well for this.
30 ounces refried beans, 1 cup sour cream, 4 ounces chopped green chiles, 4 ounces cream cheese, 1 ounce taco seasoning
Stir in ½ cup of the Mexican cheese.
1½ cups shredded Mexican cheese blend
Spread the mixture into the pan. Top with the remaining shredded cheese.
Bake for 22-26 minutes, until the cheese is melted and the beans are warm.
Top with tomatoes and cilantro, and serve with tortilla chips.
