Preheat oven to 425°F. Line a baking sheet with foil and grease lightly with cooking spray; set aside.

In a very large bowl, combine the chicken, bread crumbs, scallions, ginger, garlic, egg, sesame oil, soy sauce, Sriracha, and salt until evenly incorporated. Form the mixture into 1 1/2 -inch balls and arrange on the prepared baking sheet. Bake until golden brown and cooked through, about 13 to 15 minutes, flipping over halfway through baking. Remove from the oven and set aside.

To make the sauce, in a medium bowl, whisk together the soy sauce, orange juice, and brown sugar. Set a large skillet, with high sides, over medium-high heat with 1 tablespoon oil. Once hot, add in the ginger, garlic, and chiles. Cook for about 1 to 2 minutes, until fragrant. Stir in the rice wine vinegar, the orange juice mixture and the orange peels. In a separate bowl, stir together the water and cornstarch until smooth. Whisk the cornstarch water into the orange sauce, and cook until the sauce has thickened, about 5 to 8 minutes.

Add the cooked meatballs to the sauce and gently toss until evenly combined. Cook for about a minute or so to warm the meatballs through. Serve over brown rice and sautéed snow peas and garnish with sliced scallions.
