Optional Step 1: Cut the chicken into bite-sized pieces. Shake in a bag with coconut flour to coat (or toss in a large bowl). Heat the coconut oil in a large skillet over medium-high heat. Pan-fry the chicken in coconut oil for about 2 minutes per side to brown (it won't be cooked through).
In a medium bowl, combine the coconut aminos, honey, tomato paste, ginger, garlic, and red pepper flakes to be used as your sauce.
Place chicken in the slow cooker (can use pan-fried pieces or even leave the chicken breasts whole & shred them after cooking... the choice is yours!). Top the chicken with cashews & sauce.
Cook on "low" for 3-4 hours, and top with chopped green onion.
