In the bowl of your mixer, whisk together the All-Purpose Flour (4 cup) and Salt (1 teaspoon). Fit the mixer with the dough hook attachment. Add the Water (1 1/4 cup) and the Vegetable Oil (1 tablespoon) and knead until the mixture becomes a smooth, elastic dough.
Form the dough into a ball. Place it back in the mixing bowl. Cover with a dish cloth and let rest for 45 minutes.
Place the Ground Beef (1 pound), Sweet Onion (1) and Pickles (1/2 cup) in a bowl and mix to combine.
Add the Egg (1), Ketchup (3 tablespoon), Worcestershire Sauce (1 tablespoon), Garlic Powder (1/2 teaspoon), Salt (to taste) and Freshly Ground Black Pepper (to taste) and mix again.
Grease a large casserole dish with Vegetable Oil (to taste) and set aside. Preheat the oven to 425 degrees F (218 degrees C).
Halve the dough. Roll one half of the dough out onto a floured work surface into a rectangle. Spread the meat mixture on top of the dough. Sprinkle Shredded Cheddar Cheese (1/2 cup) on top of the meat mixture.
Roll the dough up from the long side into a log. Use a sharp knife to cut the log into 2-inch
rolls. Place the rolls, swirls sides up into the prepared greased baking dish.
Repeat with the other half of the dough, Shredded Cheddar Cheese (1/2 cup) and meat mixture.
Sprinkle remaining Shredded Cheddar Cheese (1/2 cup) over the top of the rolls, then place in the oven and bake for 30 minutes.
Remove from oven and lightly spritz water over the tops of the rollups. Cover with a clean dishtowel and let stand for 5 minutes. Uncover and serve with ketchup on the side.
