Tips For Success:
The more shallow the baking dish, the more caramelized the end result will be. I've tried this with both shallow and deep dishes and prefer the more shallow dish.
Don't over stir: Using canned beans means that beans have already been cooked to a very soft stage. During anytime during the preparation process, stir the beans gently to combine ingredients. If you over-stir the beans, they can become mushy.
