Combine the chicken and flax with your hands. It will be very sticky. I always find ground chicken annoyingly sticky but it was on sales so I went with it.
1 lb ground chicken breast, ⅔ cup ground flax
In a large nonstick skillet over medium-high, heat the oil. Form the chicken mixture into small balls (around 15) and add them to the skillet.
1 tablespoon olive oil
Turn the meatballs to seal on 2-3 sides as they brown. (I wish I took a pic of this but my hands were just too messy! )
Once the meatballs are set, lower the temperature to medium-low and cover so they begin to cook through.
While the meatballs are cooking, whisk together the almond butter, vinegar, sesame oil, tomato paste, and red pepper flakes. It will be on the thick side. A splash or two of water is fine to add to loosen it up.
2 tablespoon almond butter, 1 teaspoon sesame oil, 2 tablespoon tomato paste, 1 teaspoon red pepper flakes, 1 tablespoon apple cider vinegar
Pour the sauce over the meatballs and roll around to coat. You can continue to cook for a minute or two but the sauce will thicken even more.
Pour the meatballs into a bowl and top with additional red pepper flakes to taste.
