Preheat the oven to 375 degrees. Grease a 9x13-inch baking pan with nonstick cooking spray.
In a large mixing bowl, combine the turkey, eggs, bread crumbs, onion flakes, oregano, cumin, and paprika. Mix the ingredients until well combined.
Form the meat mixture into a loaf about 8x5 in the middle of the prepared pan. Bake for about 45 minutes or until an internal temperature of 165 degrees is reached. Remove to a cutting board. Slice and serve.
To cook in the slow cooker:
Fold a piece of foil 12X9 inches. Spray the foil with nonstick cooking spray.
Prepare the meat mixture as directed above. Form it into an 8x5 loaf and transfer to the foil sheet. Use the foil sheet to lower the loaf into the slow cooker.
Cook on low for 3 hours or until an internal temperature of 165 degrees is reached. Using the sling, remove the meatloaf to a cutting board. Slice and serve.
The meatloaf can be frozen prior to baking. Simply wrap the loaf in aluminum foil and place in a labeled ziptop freezer bag. Prior to serving, thaw the loaf completely in the refrigerator and proceed with the baking directions.
