Whisk together the milk, pimiento cheese, eggs, salt, chipotle peppers and adobo sauce.
Add black beans, corn, green onions and cilantro to the pie plate.
Pour the egg mixture over the top.
Sprinkle the top with cheddar cheese.
Bake for 25-30 minutes until the center is set.
Let stand for 5 minutes before serving.
Serve with extra chopped cilantro, salsa and fresh sliced avocado if desired.
