Definitely could use more hamburger.
I layered the sauce than some potatoes than some sauce, I repeated until all sauce and potatoes were used up, into a bowl. I added the meat than mixed together.
As I layered the potatoes into the casserole dish, I put shredded cheese in between the layers. The top layer of cheese I saved until the casserole was fully cooked and cooked an additional 5 minutes.
Would work great as a side to a salad.
