Cook noodles according to package directions, drain, and set aside.
In a small bowl, whisk together soy sauce, sesame oil, rice vinegar, maple syrup, and ginger to create the sauce.
Heat vegetable oil in a large skillet or wok over medium-high heat.
Add tofu cubes to the skillet and fry until golden brown on all sides, approximately 8 minutes, then remove and set aside.
Add garlic and red pepper flakes to the same skillet and sauté for 30 seconds.
Add shredded cabbage and carrots to the skillet and stir-fry for 3 to 5 minutes until cabbage is wilted but remains crisp.
Return the tofu to the skillet and add the cooked noodles and the prepared sauce.
Toss all ingredients together for 2 minutes until thoroughly heated and coated in sauce.
Garnish with sliced green onions and serve immediately.
