Preheat oven to 350 degrees Fahrenheit. Spray an 8x8" baking dish with nonstick cooking spray. Stir all ingredients, except the shredded cheese, together in a large bowl.

Spread into prepared pan (pan will be full) and bake, covered with aluminum foil for approximately 35-40 minutes, or until heated through. Remove the foil, sprinkle with cheese and place back in the oven for about 5 minutes, or just until cheese is melted. Serve with sliced jalapeños, diced tomatoes, sour cream, crushed tortilla chips, etc.
