Add all meatball ingredients to a large bowl. Stir with a spoon until completely combined.
Cover the bowl with a lid or cling wrap, and chill in the refrigerator for at least 20 minutes.This helps the meatballs retain their shape when forming a ball! Using a mini ice cream scoop or a small spoon, scoop out portions of the ground turkey mixture.
Add a bit of non-stick cooking spray to your hands, and roll the scoops into meatballs.
Spray non-stick spray (or pour another tsp. of extra-virgin olive oil) onto a large skillet. Add in the meatballs, and cook on medium heat for about 8 minutes, until they are browned evenly on the outside. Remove and set aside.The meatballs won't be cooked all the way through, but they'll finish cooking in the sauce later. Add the grated/minced onions to the same skillet. Sauté until they soften, about 5 minutes.
Add in the minced garlic and red curry paste. I normally remove the pan from the heat here, because the red curry paste can splatter a bit.
Break up the red curry paste with a spoon, then immediately pour in the can of coconut milk. Return your pan to heat and stir until ingredients are fully incorporated.
Season with bouillon powder, sesame oil, and rice vinegar. Taste, and adjust for your preference as necessary.
Add the meatballs back to the sauce. Cut the heat on low, cover the skillet, and simmer for about 12-15 more minutes until meatballs are completely cooked through. Serve over rice and veggies. Enjoy!
