Overnight Breakfast

I saw this idea on pinterest and couldn't wait to try...doesn't it look delicious? I put in diced potato, mushroom, onions, green pepper, bacon and cheese. Then you dump, a mixture of eggs and milk on top and let cook on low all night.
Well... I think this recipe will need some tweaking before I can dish out the recipe cards... It came out to dry and not enough flavor...
Any suggestions on what to add? Sour cream? Cream of .... Something soup? I've got to make this one work!
