½ tsp crushed red pepper flakes (more if you like it spicy!)
Kosher salt, freshly ground pepper
Instructions
Using your hands gently mix garlic, chicken, soy sauce, ginger, 4 scallions, and ¼ cup broth in a medium bowl just to combine. Scooping out by the tablespoonful, form mixture into 1˝-diameter meatballs.
Heat oil in a large skillet over medium-high heat. Add meatballs and cook, turning occasionally, until golden brown all over, 8 to 10 minutes. Transfer to a plate.
Add spinach and red pepper flakes in same skillet, season with salt and pepper, and cook until spinach is just starting to wilt. Add meatballs and remaining broth. Bring broth to a boil, reduce heat, and simmer until meatballs are cooked through, 5 to 8 minutes. Serve sprinkled with more scallions.
