Heat a large sauce pan to medium high heat and coat with oil. Add the onions and season with your Salt and Pepper + Three Chiles. Cook until the onions are softened and beginning to brown. Add your can of Pabst Blue Ribbon and your minced garlic and stir it in. Simmer for about 4 more minutes. Add your brats and let them braise for 6 to 8 minutes. Remove from the heat and set aside.
Heat a large skillet or griddle to medium high heat and coat with oil. Remove your brats from the onions and slice them in half. Cook them directly on the griddle for 4 minutes per side, or until golden brown, using a grill press to cook evenly. Remove from the heat and set aside.
On the same skillet or griddle, toast your buns for a couple minutes and set aside.
Divide the beef into 4 burger patties. Place the burgers on the skillet or griddle coated with oil and season with your Salt and Pepper + Three Chiles on both sides. Cook for 3 to 4 minutes per side using a grill press to cook evenly. Cover with a cloche and cook for 1 more minute. Add your mild cheddar cheese and let it melt. Remove the patties from the heat and set aside.
Build your burgers on the bottom bun, adding your patty, your grilled onions, and the brats sliced in half, followed by the top bun.
