Meatloaf: Preheat oven to 350 degrees and coat 9.5" x 5" nonstick loaf pan with nonstick cooking spray.
In a mixing bowl, using hands, combine all meatloaf ingredients excluding psyllium husk powder and knead together until well-incorporated. Sprinkle psyllium husk powder evenly on top of mixture and knead again. Transfer mixture to prepared loaf pan and, using hands, press into even layer. Transfer pan to oven and bake until meatloaf reaches an internal temperature of 140 degrees, about 50 minutes.
Tomato Sauce Topping: Meanwhile, in a mixing bowl, mix together all ingredients until fully combined. Set aside.
Final Steps: After 50 minutes of baking, remove pan from oven. Carefully pour excess liquid from pan into a jar to be discarded. Blot top of meatloaf with paper towel to remove excess grease. Using a rubber spatula, spread tomato sauce topping atop meat. Return pan to oven and bake until meatloaf reaches internal temperature of 160 degrees, about 10 additional minutes.
Remove pan from oven and allow to cool slightly before cutting and serving.
