First, in a large skillet, brown the ground beef while breaking it into small pieces and drain the fat and season with salt, pepper and garlic powder.
Next slice the Hawaiian rolls down the middle horizontally separating the bottom and top buns. Place the bottom buns on a parchment paper lined baking sheet (OR you can bake them right in the tray that they come in. Yes, they’re oven safe!) and spread a thin layer of Mac sauce on to them.
Now, evenly spread the seasoned ground beef onto the bottom buns.
After that, place a layer of American cheese slices down on top of the beef and add the top half of the buns
Then, using a pastry brush, spread the melted butter on top of the buns and sprinkle them with the sesame seeds.
Now bake them in the center rack of the oven at 350 degrees until the cheese is melted and the buns are lightly toasted. Watch them- they will brown very fast because of the butter. This should only take about 5-7 minutes.
While that’s baking, add the lettuce, pickles and onions onto a cutting board. Chop the vegetables together into small pieces and then mix in the rest of the Mac Sauce.
When the sliders are done, remove the top buns and add the lettuce and Mac sauce mix.
Finally place the tops back onto the sliders and enjoy!
