In a large bowl, stir together the Worcestershire sauce, water, sesame oil, soy sauce, sugar, cornstarch, and vinegar. Stir until the cornstarch is dissolved and add the chicken cubes. Toss well until all the chicken is coated and let the bowl stand, covered, for 10 minutes.
Heat a wok or a large skillet and add the coconut oil. Once the oil is hot, stir in the scallions and ginger paste. Stir fry for 1 minute and then add in the chicken and all of the sauce in the bowl. Stir fry for 4 minutes or until the chicken is fully cooked.
Stir in the water chestnuts and sugar snap peas and cook for 2 minutes. Stir in the broccoli florets and carrots and cook for another 2 minutes. Add in the hoisin sauce and sesame seeds. Stir fry for 2-3 more minutes or until sugar snap peas are tender.
Serve over hot rice and top with cashews.
