Preheat the oven to 350 degrees Fahrenheit.
In a large mixing bowl ground flax and warm water and let sit for 3 minutes. This will create a thick gel-like consistency.
In a blender or food processor, add rolled oats and pulse to create a fine oat flour with a few whole oats still remaining.
Next, wash and grate the Autumn Glory apple; dice the celery and carrot.
Add the oat flour, apple, celery, carrot, lentils, garlic, paprika, salt and pepper to the mixing bowl with the flaxseed mixture and stir until fully combined.
Add mix to a greased loaf pan and bake for 45 minutes. At 30 minutes, remove from the oven and top with ketchup or BBQ sauce of choice place back in to finish baking.
Garnish with apple slices, baked in the 350 degree oven for about 10 minutes; and then enjoy!
