Begin by finely chopping green onions, mincing garlic, and grating the fresh ginger.
Pulse the cauliflower florets in a food processor until it resembles a rice-like texture. Set aside a small portion (about 2 tablespoons) to mix into the filling for texture and flavor.
Finely mince or process the chicken breast into a coarse paste in a food processor. Alternatively, finely chop the chicken if preferred.
In a bowl, combine the ground chicken with the processed cauliflower, egg white, green onions, minced garlic, grated ginger, low-sodium soy sauce, salt, and pepper. Mix well until all ingredients are evenly distributed.
Allow the mixture to rest for 5 minutes for the flavors to meld.
Using your hands, shape the mixture into small, dumpling-sized balls or gently flatten into small discs if you prefer a dumpling pocket style.
To cook, lightly spray a non-stick skillet with cooking spray or use a minimal amount of olive oil. Heat the pan over medium heat.
Place the dumplings in the skillet in a single layer. Cook for about 3-4 minutes on each side, or until the dumplings are golden brown and the chicken is cooked through.
Remove from heat and serve immediately. These dumplings pair well with a side of light dipping sauce or a fresh salad.
