01 - Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a spatula, until browned and no longer pink, about 5 to 6 minutes. Drain excess fat if needed.
02 - Add the chopped onion, green bell pepper, and minced garlic to the skillet with the beef. Sauté until the vegetables are softened, 3 to 4 minutes.
03 - Pour in the tomato sauce, tomato paste, ketchup, Worcestershire sauce, yellow mustard, brown sugar, smoked paprika, chili powder, salt, and pepper. Stir until everything is well combined.
04 - Reduce the heat to low and let the mixture simmer uncovered for 10 to 12 minutes, stirring occasionally, until the sauce has thickened nicely.
05 - While the meat mixture simmers, butter the cut sides of the burger buns. Toast them in a clean skillet or on a baking sheet until golden brown and crispy.
06 - Pile the sloppy joe mixture generously onto the bottom halves of the toasted buns. Top with sliced dill pickles and cover with the bun tops. Serve immediately while hot.
