Preheat oven to 400°F. Adjust rack to lower third of oven. Prepare two 4x6x12-inch loaf pans with cooking spray. Alternatively, line a large roasting pan that can fit 2 meatloaves side by side with parchment in between. Set aside.
Whisk together all the glaze ingredients and set aside.
Add olive oil to a large skillet over medium heat. Once the oil is shimmering, add the onion, carrot, and celery and sauté until softened, about 8 to 10 minutes. Add the garlic and cook for 1 minute, then set aside to cool.
Once the veggies have cooled briefly, add the panko, eggs, mustard, ketchup, Worcestershire sauce, Tabasco, salt and pepper and stir with a fork to form a paste. Using your hands, gently work in the ground meats and cheese until combined.
Evenly divide the meatloaf mixture between the prepared loaf pans, packing it loosely in the pan. Cover with foil and bake in the lower third of the oven for 1 hour 15 minutes, or until an instant-read thermometer inserted in the center of each loaf registers 150°F. During the last 15 minutes of baking, liberally baste the loaf tops with the glaze and bake uncovered to hasten browning.
Rest loaves for 15 minutes before removing from pans to serving platters. Cut into thick slices and serve with creamy onion gravy, plenty of fluffy mashed potatoes, homemade spaetzle, or homemade dumplings.
