Bring a large pot of water to a boil. Add the noodles and cook until just tender, about 4 minutes -- or according to package directions. Drain the noodles, rinse briefly with cold water. When well drained, transfer to a bowl. Toss with the sesame oil, to coat lightly and set aside.
Combine the oyster sauce, soy sauce, fish sauce, cornstarch, and pepper in a small bowl and stir to dissolve the cornstarch.
In a large skillet or wok, heat 2 tablespoons of coconut oil over medium heat. Add the garlic and cook for 30 seconds, stirring, or until garlic is fragrant.
Stir in the carrots, zucchini, green onions, snow peas, green beans, mushrooms, and red pepper flakes to the skillet. Cook, stirring, for about 4 minutes.
Add the shrimp and cook until the shrimp begin to turn pink, 2-3 minutes, stirring occasionally. Once the shrimp are no longer translucent, add the noodles to the pan and stir to combine with vegetables and shrimp.
Lastly, gently toss the sauce with the noodles and vegetables until well coated; cook until the sauce is bubbly and thickened. Serve immediately.
