A buddy at work told me about them. Doesn't get much simpler. Sprinkle a layer (~1/4-1/2 cup) of dried onion flakes in a 9X13 baking dish. Spread 2 lbs. of hamburger evenly in the dish and press down into the onion flakes, covering the bottom of the dish. Season to taste and bake for 20 minutes @ 350°. Remove from oven and drain grease off. Add cheese if you want and return to oven long enough to melt cheese. You should have a perfect rectangle that you cut into dinner roll size squares. I used King's Hawaiian rolls and they were DELICIOUS! Enjoy!
They are simple and very good! Chase made homemade mac and cheese to go with it, which was delicious, but the combination felt like a rock in my belly!
Kim bought the hamburger at our only local grocery store which sells very fatty burger. Next time I'm gonna use leaner meat or possibly deer burger. I'm thinking about trying the deer burger and adding just a little water and cooking covered for half the cooking time to try and give them a "steamed" taste like White Castle. Might be worth a try? Oh, and I'll be adding a couple pickles next time too.
