    This recipe was delicious, and a hit with my children from the first bite. I made it almost as directed, using cheddar cheese and 1 1/4 c dry bread crumbs. It seemed like It was a little light on the potato side and a little heavy on the topping side. Also, there seemed to be not quite enough sauce for the potatoes. When I make this again, I will probably use 3.5 lbs of potatoes, double the sauce, and cut back on the topping a bit.
