Thoroughly butter one side of each slice of bread. Set aside.
02 -
Combine the ground beef, pepper, salt, and onion powder in a bowl and mix until the spices are evenly distributed. Shape the mixture into three separate patties to match the shape of the bread.
03 -
Preheat a nonstick skillet on medium-high heat. Cook each patty for approximately 2-3 minutes on one side, then flip and cook for another 2-3 minutes. Reduce heat to low and cook for approximately 5 more minutes until the patties are uniformly brown with no pink remaining. Verify the internal temperature reaches 71°C (160°F) using a digital thermometer.

Mix the mayonnaise, ketchup, bacon bits, relish, and sugar in a small bowl. Stir until well blended, then set aside.
05 -
Heat a second skillet on medium-low heat and place one slice of bread (butter-side down) in the skillet. Top with two slices of cheddar cheese, one beef patty, and two slices of Provolone cheese. Spread the sauce over the unbuttered side of a second bread slice and place it sauce-side down on top of the cheese.

Cook each sandwich for 2-3 minutes per side or until the bread is lightly toasted and the cheese is melted. Repeat this process for all sandwiches.

Remove sandwiches from heat and serve immediately. Enjoy!
