Preheat your oven to 180°C (350°F). Line a baking tray with parchment paper.
Finely chop the onion and garlic cloves. Roughly chop the parsley.
In a blender, combine the chicken breasts, chopped onion, garlic cloves, and parsley. Add the nettle salt, black pepper (for meatballs), red pepper powder, curcuma, cayenne pepper, mustard, honey, teriyaki sauce, and 1 tablespoon of olive oil.
Blend the mixture until well combined and smooth enough to form meatballs. Don't overmix.
Form the chicken mixture into bite-sized meatballs and place them on the prepared baking tray.
