Gently toss together the crabmeat and seafood seasoning in a medium bowl and then refrigerate.
Melt 2 tablespoons of the butter on a griddle or in a large skillet over medium heat. Add the onions, 1 tablespoon of the soy sauce and 1 tablespoon of the Worcestershire sauce and cook until the onions start to soften, about 5 minutes. Raise the heat to high, add the beef and cook, adding more butter if needed and breaking up the meat with a spatula. Stir in the remaining soy sauce and Worcestershire sauce, sprinkle with salt and pepper and continue to cook until the beef is no longer pink, about 2 minutes.
Stir in the cherry peppers and push the beef and onions over to the side of the griddle and cover with the cheese slices. Melt the remaining 1 tablespoon butter in the cleared area of the griddle, add the crabmeat and cook just until warmed through, about 2 minutes.
Spread both sides of the rolls with Have Mercy Sauce. Top the bottom half of the rolls with the beef and onion mixture and crabmeat. Cover with the top half of the rolls.
