• If you don't have cooked rice, start by making the rice. Set aside to cool to room temperature.
• Add a small beet to a medium pot of water and gently boil for about 25 to 30 minutes until cooked. Run the cooked beet under cool water to handle. Use your fingers or a small paring knife to remove any skin on the beet. Then, dice it into small pieces.
• Drain and rinse a can of low-sodium or no-salt-added black beans (or adzuki beans) and set aside. If making dried beans from scratch, cook and cool them to room temperature and set aside.

Assemble and cook the slider patties

• Put cooked and cooled brown rice and black beans into a large mixing bowl. Using clean hands, mash the brown rice and black beans together into a mushy mixture. It gets messy, so you'll want to wash your hands off when you're done.
• Add the cooked diced beets and coconut aminos to the burger mixture.
• It's important to pre-mix the dry ingredients before adding to the burger mixture. This aids in evening out the spices across the mixture. Put the black pepper, garlic powder, onion powder, ground flaxseeds, and arrowroot powder into a bowl and stir to combine with a small spoon.
• Sprinkle the dried seasoning over the burger mixture. Add the BBQ sauce over the top, and use a wooden spoon to mix well and smash up big chunks of beets and beans.
• Use your hands to form small slider patties and add them to the air fryer.
• Put the slider patties into the air fryer and cook them at 370 F (190 C) for 15 minutes. The sliders should be crispy on the outside and soft but chewy on the inside. If you don't have an air fryer, you can bake them on a parchment-lined baking sheet at 370 F (190 C) for 25 minutes. Enjoy immediately!
