In a small bowl, whisk all sauce ingredients together and set aside until ready to use.
In a large pot of boiling water, cook the noodles according to package directions; drain well.
Heat the oil in a large skillet or wok, over medium-high heat. Add in garlic, mushrooms, bell peppers and carrots. Cook, stirring frequently, until crisp-tender, about 4-6 minutes.
Stir in the egg noodles and pour the sauce over, gently tossing with tongs to combine and coat.
Divide into bowls and garnish with green onions and sesame seeds.
Enjoy!
