In a large skillet, heat oil over medium-high heat.
Add the sausage, ginger and garlic. Stir-fry for 2 to 3 minutes or until lightly browned. Add the broccoli, water and teriyaki sauce; cook and stir for 3 to 4 minutes or until broccoli is crisp-tender.
Serve over rice.
If desired, sprinkle with cashews.
