Preheat the oven to 375°F and coat a small roasting pan with nonstick spray.
Prepare the spice blend by thoroughly combining the cumin, coriander, cinnamon and cayenne in a small bowl.
Add the ground lamb, egg, yogurt, breadcrumbs, parsley, garlic, salt, Moroccan spice blend and a few grinds of black pepper to a mixing bowl.
Combine thoroughly and form the mixture into a small, rounded loaf (about 6 x 3-1/2 inches) and place it on the prepared roasting pan.
Bake for 25 minutes or until a thermometer inserted in the center of the meatloaf registers 150°F. Remove from the oven, tent loosely with foil and allow the meatloaf to rest for 10 minutes before slicing.
While the meatloaf bakes, combine the tomato sauce, tomato paste, yogurt, garlic and Moroccan spice blend in a small saucepan. Season to taste with salt and pepper and cook over medium-low heat for 10 minutes, stirring occasionally.
Remove the sauce from the heat, stir in the lemon juice and transfer the mixture to a small serving bowl.
Tips for Making This Recipe
