In a mixing bowl, combine the ground beef and ground turkey with breadcrumbs, egg, grated Parmesan cheese, minced garlic, dried Italian herbs, salt, and pepper. Mix until evenly blended.
On a baking sheet lined with parchment paper, shape half of the meat mixture into a rectangle about 1 inch thick.
Spread pesto sauce over the meat layer, then sprinkle shredded mozzarella cheese on top.
Place the remaining meat mixture over the mozzarella layer and press down to seal the filling within.
Drizzle olive oil over the top and bake for 50-60 minutes, or until a meat thermometer reads 160°F (70°C).
Allow the meatloaf to rest for about 10 minutes before slicing.
Slice the meatloaf into thick pieces and serve warm, optionally with roasted vegetables or creamy mashed potatoes.
Notes
For an eye-catching presentation, drizzle extra pesto over the sliced meatloaf and garnish with fresh basil leaves.
