Veggie Burger

  • 1 Tbsp ground flax seeds
  • ¼ cup water
  • 46 Tbsp olive oil, divided (see notes)
  • 1 bell pepper, coarsely chopped
  • ½ white onion, coarsely chopped
  • 1 cup cooked sweet potato
  • 3 chipotles in adobo sauce
  • ½ cup cilantro, fresh
  • 2 tsp sea salt
  • ½ tsp black pepper
  • 2 tsp granulated garlic
  • 1.5 cups cooked white rice (I used jasmine)
  • ¾ cup buckwheat flour + more for dusting (see notes)


  1. Combine the water and green lentils in a sauce pan and bring to a boil. Let cook for about 20 minutes. Strain any remaining water and set aside.
  2. Combine the flax seeds and water in a small bowl for the “egg” and place in the refrigerator.
  3. Heat a skillet to medium-high heat and add the oil. Once hot, sauté the peppers and onions for 5-8 minutes or until softened.
  4. Add the sautéed veggies, half the lentils, chipotle peppers and sweet potato to a food processor and coarsely chop.
  5. Add the cilantro, salt, pepper, garlic and flax egg and pulse until everything is combined.
  6. Add the mixture to a large bowl and then add the remaining lentils, cooked rice and buckwheat flour and mix together.
  7. Place in the refrigerator for 15-20 minutes to set.
  8. Scoop about 1/3 cup of batter out and roll it completely in buckwheat flour. Use your hands to form a ½ inch thick patty. If it’s too sticky then dust with more buckwheat.
  9. Heat a skillet to medium heat and add 2-3 tablespoons of olive oil. Once hot, cook the burgers for 2-3 minutes a side. I suggest cooking patties while you are rolling out more.
  10. Add your favorite burger toppings and enjoy!


  • If your batter is too watery add more buckwheat flour
  • I recommend dusting your hands with buckwheat when forming the patties. You want to roll them in flour almost as if you were making biscuits. Don’t be shy with the flour.
  • Buckwheat is highly absorbent. You may need to add more oil to the pan when frying the burgers.
  • These are great for freezing and reheating.
