In a small bowl, whisk together brown sugar, soy sauce, grated ginger, sesame oil and Sriracha.
Heat olive oil in a large skillet over medium high heat. Add minced garlic and cook, stirring constantly until fragrant, about 1 minute. Add ground beef and cook until browned, about 3-5 minutes; drain excess fat.
Spiralize or grate zucchini; thinly slice green onions. Add zucchini, green onions and soy sauce mixture to the skillet. Stir until well combined, allowing to simmer until heated through, about 2 minutes. Add cooked pasta; toss and allow to heat through.
