Prepare salmon: Remove the skin on the salmon and cut it into 1-inch, bite-sized cubes. Sprinkle the salmon evenly with salt and pepper.
Prepare vegetables: Chop onion, pepper, zucchini, mushrooms, and carrots and set aside.
Make stir fry sauce: In a small bowl, whisk together corn starch, soy sauce, honey, sriracha, sesame oil, garlic cloves and 2 tbsp of water and set aside.
Cook salmon: Heat a large wok or skillet over medium heat and add the olive oil. Add in salmon cubes and cook for 3-5 minutes, or until cooked to medium. Gently stir and shake the pan to move salmon. The salmon is fragile and can fall apart easily. Allow the pan to sear the salmon for a strong, golden crust. Remove the salmon and place in a separate bowl. Tent to keep warm.
Sauté vegetables: Add the vegetables to the same wok or skillet and cook over medium heat for 5-7 minutes, until they are tender but still crisp.
Add sauce: Add the soy sauce mixture, reduce heat to medium-low and cook for an additional 2-3 minutes, or until the sauce has thickened and turns glossy.
Combine with salmon: Gently add the salmon back in and toss lightly to combine.
Garnish and serve: Garnish with green onions and sesame seeds. Enjoy!
