Preheat the oven to 375°F. Line a baking sheet with parchment paper.
In a large bowl, combine the ground pork, breadcrumbs, egg, onion, garlic, thyme, salt, and pepper. Mix until evenly blended, then shape into a loaf about 8 inches long.
Lay the bacon slices across the loaf in overlapping strips to cover the top and sides like bandages. Place the wrapped loaf on the baking sheet.
In a separate bowl, toss the carrots, parsnips, and sweet potatoes with the olive oil and rosemary. Spread the vegetables around the meatloaf on the same baking sheet.
Bake for 50 to 55 minutes, until the meatloaf reaches 160°F inside and the bacon is crisp. Remove from the oven and let the meatloaf rest for 5 minutes.
Place sliced olives on the meatloaf to form eyes. Slice the meatloaf and serve with the roasted vegetables.
