Pretty easy to make and enjoyed by all, even my picky husband didn't object. :) I substituted a bar of neufchatel for the cottage cheese and did 2 cups each of the mozzarella & cheddar. It also did not sit overnight. We had unexpected out-of-town company drop by and I took a chance and baked it right after assembly for our guest. Don't know what difference the overnight treatment would have made, it was great without the wait.
