In a large bowl, combine the ground beef, chopped onion, minced garlic, Worcestershire sauce, egg, Italian breadcrumbs, ketchup, salt, pepper, onion powder, garlic powder, Italian seasoning, and smoked paprika. Gently mix everything together with your hands - don't overwork the meat or the sliders will be dense and tough.

Form the meatloaf mixture into 16 mini slider-sized patties. Place them on a wire rack set over a baking sheet - this helps them cook without sitting in grease.

Mix together the ketchup, BBQ sauce, and mustard. Spread this sauce mixture over the top of each meatloaf patty.

Bake at 400 degrees for about 30 to 35 minutes, or until the beef is fully cooked. Check the internal temperature with a meat thermometer - it should reach at least 165 degrees.

While the meatloaf patties are baking, spread mayo or butter on the insides of the Hawaiian slider buns. Toast them in a skillet until golden brown.
