Step 1

Preheat oven to 400 degrees then line a baking sheet with foil and spray with nonstick spray. Add all meatball ingredients except half the green onions (save those for garnish) and toppings into a large bowl then mix with hands until just combined (mixture will be very sticky.) Roll into 16 balls then place onto prepared baking sheet and bake for 16-18 minutes, or until meatballs are cooked through.

Step 2

Meanwhile, combine all Kung Pao Sauce ingredients except gluten-free flour + water in a medium-sized saucepan over medium-high heat then bring to a boil. Turn heat down to medium then drizzle in flour/water mixture and whisk to combine. Continue simmering, whisking occasionally, until sauce has slightly thickened, 3-4 minutes. Add cooked meatballs then stir to coat and turn off the heat - sauce will  continue to thicken as it cools.

Step 3

Transfer meatballs to a platter then top with reserved chopped green onions, chopped peanuts, and sesame seeds.
