2 cups mashed potatoes (hot – about 4 medium potatoes)
1 cup shredded cheddar cheese
Cook and prepare the potatoes; and mash.
Preheat oven to 350F.
While the potatoes are cooking in a large skillet over medium-high heat brown the burger and onions in the olive oil until burger is no longer pink inside, salt and pepper to taste; and drain if needed. Add the steak sauce and continue cooking until mixture is bubbly and heated through. Place the meat mixture in the bottom of a 1 ½ quart casserole dish lightly sprayed with cooking spray.
Fold the shredded cheese into the mashed potatoes and spoon the mixture over the top of the meat.
