Place noodles in a large bowl. Cover with boiling water; let stand, tossing with Grip & Grab frequently until soft and pliable, about 7–10 min. Drain and rinse with cold water; place back in bowl.
Meanwhile, thinly slice peppers and onion; add to bowl with cooled noodles.
Cut chicken into bite-size pieces.
Heat oil in a Wok over medium-high heat. Add chicken, shrimp, and seasoning. Stir-fry until cooked through, 3–5 min. If the seasoning starts to stick, add a bit of water to help loosen the bits from the wok.
Add to bowl with noodles. Drizzle dressing on top, using Grip & Grab gently toss to mix. Add toppings, if desired.
