Dice up red bell pepper and add to large mixing bowl with organic meat, cilantro, spinach, flaxseed and seasonings.
Use your hands and mix thoroughly, then form into 4-5 patties.
Heat skillet (or grill) on medium with avocado oil. Add patties once oil is hot, but not smoking. Cover, and let cook about 5-7 minutes on either side, or until cooked through.
Once done, build burgers with butter lettuce, tomato, avocado, red onion and condiments.
