This meatloaf and gravy is meaty ... To ensure the gravy is gluten-free as well, use chickpea flour instead of all-purpose flour and a gluten-free Worcestershire sauce such as Lea & Perrins.
use mashed lentils or chickpeas mixed with finely chopped carrots, onions, garlic, and nutritional yeast. Blend everything with your flaxseed mixture and bake it like traditional meatloaf.
