In a small saucepan, add lentils and water. Bring to a boil, cover and cook for 5 minutes.
Transfer to a large bowl along with ground turkey, quick oats, zucchini, egg, soy sauce, onion powder, garlic powder and pepper. Mix well with your hands.
Line slow cooker with unbleached parchment paper and spray with cooking spray. Transfer meat mixture and form into a meatloaf shape. Cover and cook on Low for 6 hours or on High for 3 hours.
Holding onto the parchment paper flaps, remove meatloaf and slice. Serve warm or cold with a grain of choice or salad.
Notes
Store: Refrigerate in an airtight container for up to 5 days.
Freeze: Fully cook, cool completely, slice and freeze in an airtight container for up to 3 months. Thaw in a refrigerator overnight. Reheat in a microwave or in the oven at 375 F for 10 minutes.
Ground turkey: Use ground turkey that is not extra lean, otherwise meatloaf will be dry.
Zucchini: With zucchini, meatloaf will be more lighter, softer and juicier; however, I tried without and it turned out very good as well.
