Preheat oven to 400 degrees.Chop all of the fresh vegetables (peppers, onions, celery) into a small dice and mince the garlic. Over medium-high heat, melt 6 tablespoons butter. Once butter begins to start browning, add the diced vegetables and garlic. Add about 1 teaspoon salt. After these have cooked for a few minutes add 1 tablespoon Worcestershire sauce, 1 teaspoon black pepper, 1 teaspoon nutmeg and 1 teaspoon cayenne pepper. If you like it hot, add a couple shakes of your favorite hot sauce. Next add about ½ cup of ketchup. Continue cooking and stirring for a few more minutes. Remove from heat.After allowing the mixture to cool for a couple of minutes, add about ½ cup of milk. Stir until combined. Next add at least 1 cup of breadcrumbs. Continue adding breadcrumbs and stirring until mixture is a nice, thick paste. In a large mixing bowl place the ground beef and pork. Whisk 3 eggs and add to the meat. After allowing the pasty vegetable mixture to cool down a bit, begin incorporating it into the meat. Keep working all of the Cajun-Vegetable mix into the meat until all is blended well.Spray a sheet pan with some non-stick cooking spray. Next, using your hands, form your meat mixture into a loaf on the sheet pan. Make the loaf around 6-8 inches wide and about 1 ½ inches thick. In a small bowl or measuring cup, mix together ¾ cup of ketchup with about 2 tablespoons honey. Slather this sauce over the whole meatloaf.Place in a 400 degree oven for about 40 minutes.
