Preheat oven to 400F. In a large bowl, add all turkey meatball ingredients. Mix until everything is incorporated. Then, use a large cookie scoop to measure out 1.5-2 tbsp per meatball. Roll into balls and place on a baking sheet.
Transfer meatballs to the preheated oven and bake for 15 minutes, or until the internal temperature reaches 165F.
While the meatballs are cooking, bring a large, high-sided pan to medium heat. Add enough oil to coat the bottom of the pan. Once hot, add the onion and bell pepper. Cook for 5-6 minutes, stirring occasionally.
Add garlic and cook for another minute until fragrant. Add curry paste and pumpkin, stir to combine and cook for 2 minutes. Lower heat to a simmer and add coconut milk, coconut aminos and season with salt, pepper, pumpkin pie spice, and cayenne pepper. Let simmer for 10 minutes.
Mix in the tapioca flour. Add cooked turkey meatballs. Continue cooking for 5 more minutes until the sauce has thickened and the meatballs are warm.
Serve over white rice and top with chopped cashews/peanuts and cilantro. Enjoy!
