Line a large baking tray with heavy-duty aluminum foil.
Spray the baking sheet with non-stick cooking spray.
Prepare your veggies: chop the onion, red pepper and garlic and set aside.
Put the ground meats into a very large mixing bowl.
In a separate, smaller mixing bowl, beat the eggs and add the spices, Worcestershire sauce and milk and whisk to combine.
Add the veggies, egg mixture and bread crumbs to the meat mixture and with clean hands, combine well, mixing only enough so that everything is incorporated.
Transfer a little more than half of the meatloaf mixture to the prepared baking tray and shape into a loaf.
Make a trench down the center of the loaf using your hands.
Add the 3 hard-boiled eggs to the trench.
Cover with rest of meatloaf mixture, shaping well.
