Heat the oven to 400°F. Line a rimmed baking sheet with parchment paper.
Add the ground turkey, egg, almond flour, diced onion, 1 tablespoon parsley, cumin, coriander, paprika, cinnamon, ½ teaspoon salt, and black pepper to a large bowl. Mix gently until just combined. Shape the mixture into a compact loaf in the center of the baking sheet.
Toss the carrot sticks with the olive oil and the remaining ¼ teaspoon salt. Arrange them around the meatloaf in a single layer.
Bake for 35 to 45 minutes, until the carrots are tender and the center of the meatloaf reaches 165°F. Let the meatloaf rest for 5 minutes before slicing.
While the meatloaf bakes, whisk the tahini and lemon juice in a small bowl. Add the water a little at a time until the sauce is smooth and easy to drizzle.
Slice the meatloaf and serve it with the roasted carrots. Drizzle the tahini sauce over the top and finish with the remaining parsley.
