Spray a wok or skillet generously with non-stick cooking spray, set it over medium heat and allow it to get very hot. Add garlic and cook until garlic is browned on both sides. Remove.
Add zoodles, carrots and edamame, along with sesame oil, soy sauce, sriracha sauce (if using) and shrimp.
Toss with tongs for one to two minutes until heated through. Garnish with scallions or sesame seeds.
