Pat the salmon cubes dry with a paper towel and season lightly with salt and pepper.
In a small bowl, mix the teriyaki sauce, sesame oil, minced garlic, and ginger and set aside.
In a large non-stick skillet or wok, heat 1 tablespoon of vegetable oil over medium-high heat.
Add the cubed salmon to the skillet and cook for about 4-5 minutes until golden brown and cooked through. Remove the salmon from the skillet and set aside.
In the same skillet, add the remaining tablespoon of oil. Add the sliced bell peppers, snow peas, and broccoli. Stir-fry for about 3-4 minutes until the vegetables are vibrant and tender-crisp.
Return the cooked salmon to the skillet, pour the teriyaki sauce mixture over the salmon and vegetables, and gently toss to combine. Cook for another 1-2 minutes until everything is well coated and heated through.
Sprinkle with chopped green onions and sesame seeds. Remove from heat.
Notes
