Line a baking sheet with foil. Place Hawaiian sweet rolls onto foil and slice entire slab of rolls across lengthwise. Open like a book and set aside.
In a large skillet, brown ground beef completely. Once it's mostly browned, stir in green onion, garlic powder, Worcestershire, salt and pepper. Continue cooking until completely browned. Pour overtop the bottom half of the rolls and spread evenly. Top with cheese and place under the broiler on low until the cheese is just melted. Remove from oven. Turn broiler off.
Microwave bacon to crisp up and cut into smaller pieces to fit on each slider. Add bacon pieces on top of melted cheese and add the tops of the rolls. Return to warm oven and keep warm until ready to serve. (You just want to warm the tops of the rolls a touch, about 3 minutes.
Remove from oven and serve with any desired toppings.
