"This was good, but caramelizing the onion and cooking the bacon took more time than we thought it was worth. We would have been just fine with gravy instead of all the fancy toppings."

"Delicious! I prepared this dish two nights ago and my 8 year old is still raving about it! And the fact that its lower in fat is just icing on the cake!"
