1-First, prepare all ingredients by slicing the pickles and cheese while preheating your oven to 350°F. Lightly toast the sweet rolls in the oven for about 5 minutes to add texture. Then, layer the ham, cheese, and pickles evenly on the bottom halves of the rolls in a greased baking pan.

2-Next, replace the top halves of the rolls to assemble the sliders. Melt the butter in the microwave and mix in the finely chopped onion and Dijon mustard to create the topping. Drizzle this mixture over the assembled sliders and cover the pan before baking.

3-Bake covered for 10 minutes, then uncover and bake for another 5 to 10 minutes until golden brown. For adaptations, use pulled pork instead of ham for a twist, or opt for vegan cheese to fit dietary needs. This method keeps the sliders simple yet delicious, with a total preparation time of just 30 minutes.
