Preheat oven to 350 degrees.
1. In a large bowl, combine all ingredients and mix well.
2. Grease a 9 x 12 shallow glass baking dish. Spread the mixture evenly in the pan. Bake at 350 degrees for about 50 minutes, until the sides are turning golden brown.
NOTE: Alison suggests that you use the shallow baking dish rather than a tall-sided casserole dish. The shallow dish allows the ingredients to set more firmly into a hearty casserole. We found that Alison is exactly right about this! Our casserole baked in the smaller, taller dish was runny. Alison's casserole baked in the shallow dish was perfect!
