Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper for easy cleanup.
In a medium mixing bowl, combine the ground turkey, egg, almond flour, tomato paste, garlic powder, onion powder, thyme, rosemary, sea salt, and black pepper.
Gently mix the ingredients by hand until just combined, taking care not to overwork the meat to ensure a tender texture.
Shape the turkey mixture into a compact loaf and place it on one side of the prepared baking sheet.
Place the broccoli florets and sliced bell peppers on the other side of the sheet, drizzling them with olive oil and a pinch of salt.
Bake for 25 to 30 minutes, or until the meatloaf reaches an internal temperature of 165°F and the vegetables are tender with slightly charred edges.
Remove from the oven and let the meatloaf rest for 5 minutes before slicing into thick pieces and serving with the roasted vegetables.
