Here you go guys:

Take 3 medium-large potatoes, cut into fairly thin medallions, toss in a bowl with oil/salt/pepper/garlic powder

Spray a 9"x13" casserole dish with non stick spray and evenly distribute potatoes along the bottom, overlap is fine

Take your ground hamburger mix, I like leaner for hamburger steak, and make patties

Coat patties in flour and sear in a pan with oil. After both sides are browned, lay the patties on top of the potatoes.

Slice up onions and put them on top of the patties. Season with salt and pepper.

Make 1 package of brown gravy that you find at the store, them pour the gravy over the hamburger and potatoes. Cover with tinfoil and bake at 350 for about 50 minutes until the potatoes are tender.
