Preheat your oven to 400°F (200°C) for even baking.
In a large mixing bowl, combine the ground chicken, kosher salt, smoked paprika, riced cauliflower, chopped onion, parsley, minced garlic, and the egg. Mix until just combined.
Form the mixture into meatballs about 1 ½ inches in diameter.
Spray your baking sheet with olive-oil cooking spray. Place the meatballs on the sheet, leaving space between each one. Bake for about 20-25 minutes, or until the internal temperature reaches 165°F (74°C).
While the meatballs are baking, pour the harissa sauce into a saucepan and heat over medium-low until warmed through.
Once the meatballs are cooked, remove them and toss in the warm harissa sauce. Serve and enjoy!
