In a large bowl, whisk together egg with Italian seasoning, salt, pepper and red pepper flakes.
Add carrots and ground meat to the bowl. Using your hands, mix the ingredients together thoroughly but don't overwork it. With a small ice cream scoop or a tablespoon, scoop out and roll the meat into balls until 18 meatballs are made and the meat is gone.
Heat a medium skillet over medium-high heat. Add oil to the pan and heat 4 minutes, and then add the meatballs to the pan.
Cook meatballs 5 minutes. Then, flip to cook on the other side another 5 minutes. Rotate the meatballs a few more times in the pan, cooking 1-2 minutes until cooked through. Remove meatballs from the pan to a warm plate.
Add ¼ cup water to the skillet with riced cauliflower. Cook 5 minutes until softened, and then add lemon juice and mint leaves. Stir to combine.
Divide the meatballs and cauliflower rice into 4 even servings. Next, place them in meal prep containers with fresh lemon wedges and store in the fridge until you're ready to eat them.
