Preheat oven to 375 degrees. In a large bowl, thoroughly combine the meat, cheese, bread crumbs, garlic and onion powder, parsley, Italian seasoning, eggs and milk. Place a foil-lined grate over a shallow baking pan and poke holes in the foil for the fat to drip through. Make 15 1/3-cup meatballs and place on foil. Bake for 45 mins. While the meatballs are baking, add the chili sauce, jelly, hot sauce and bourbon to a saucepan and simmer until the jelly is liquefied. Add the completed meatballs to the sauce and coat each completely. Serve on a slider bun while hot.
