Lisa @ The Cutting Edge of Ordinary - recipe from The Big Red Kitchen
½ cup dried onion flakes
2 pounds ground chuck (80/20 ground beef)
½ teaspoon seasoning salt
6 slices cheddar cheese
24 small party rolls or slider rolls
24 dill pickles

Evenly spread the onions on the bottom of a 9x13 inch-baking dish. Gently press the ground beef on top of the onion flakes. Press evenly, making one giant pattie. Sprinkle with seasoning salt. Bake at 400 for 20 minutes. Using a paper towel, pat the excess grease from the top of the ground beef. (My note - there was way too much grease to pat these with a paper towel. I eneded up pouring the grease into an old pickle jar while my husband held the hamburger with with a spatula so it wouldn't fall out. Worked out pretty well). Top with cheddar cheese and return to the oven for 2 minutes, or just enough to melt the cheese. (I didn't return these to the oven, the heat of the burger melted the cheese). Remove from the oven and let stand for 5 minutes. Cut into 24 patties.

Arrange the bottoms of the rolls on a large platter and using a spatula, place the patties on the bottom of the rolls. Top with a dill pickle if desired, then slap a top on those bad boys. Serve immediately.
