Hash Brown Casserole - zero calories

A really easy one from Andrea. Thank you Andrea! Our suspicion is that the sour cream and cheese magically counteract each other resulting in the zero calories.

a package of frozen hash browns... not hash brownies! 
a can of cream of mushroom soup
a cup of diced ham.. I cheat and add more than this.. your call!
a half cup of chopped onion... cheated here too. love onions!
a cup of sour cream. I try to get the good stuff but Sandy usually catches me.. sigh.
half of a chopped up pepper. red, green, yellow, orange, whatever as long as its sweet
a half cup of melted butter
a cup and a half of shredded cheese
a ridiculous amount of black pepper. Use your own judgement but I put in lots!
