Step 1: Place the chicken in a medium bowl. Place the tamari or soy sauce, wine or sherry, cornstarch, sesame oil, salt, and pepper in a small bowl and whisk until the cornstarch is dissolved. Drizzle 2 tablespoons of the mixture over the chicken and toss to combine; set the chicken aside.
Step 2: Add the vinegar, sugar, and sambal to the remaining marinade and whisk until the sugar is dissolved; set this sauce aside.
Step 3: Stir-fry the vegetables and aromatics. Heat a flat-bottomed wok or large frying pan over medium-high heat until very hot (a flick of water should sizzle and evaporate right away), about 2 minutes. Drizzle in 1 tablespoon of the oil, add the bell peppers and celery, and season with salt. Stir-fry with a metal spatula until crisp-tender and browned in spots, about 4 minutes. Add the garlic and ginger and stir-fry until fragrant, about 30 seconds. Transfer to a plate.
Step 4: Drizzle the remaining 2 tablespoons oil into the pan. Add the chicken and spread into an even layer. Let cook undisturbed until golden-brown and seared on the bottom, 3 to 4 minutes. Stir-fry until just cooked through, 2 to 3 minutes more.
Step 5: Return the vegetables to the pan and stir-fry with the sauce. Add the reserved vegetables and peanuts to the pan. Re-whisk the reserved sauce to dissolve the cornstarch. Pour into the pan and stir-fry until the sauce thickens, is glossy, and evenly coats everything in the pan, about 1 minute more. Sprinkle with the scallions if using and serve immediately with rice.
Step 6: Storage: Leftovers can be refrigerated in an airtight container for up to 4 days.
