Instructions:
1. Cook the noodles according to package instructions. Drain and set aside.
2. In a medium-sized bowl, add soy sauce, maple syrup, and sesame oil. Whisk until well combined.
3. To marinate tempeh, combine cubed tempeh with 2 tbsp of soy sauce and let it sit for 10-15 minutes.
4. Heat 1 tbsp of olive oil in a large wok or large skillet over medium-high heat. Add marinated tempeh and stir-fry until golden brown. Remove from the skillet and set aside.
5. In the same skillet, add more olive oil if needed. Stir in garlic and ginger until fragrant. Add shiitake mushrooms, bell peppers, onions, broccoli, and seasonings. Stir-fry for 3-4 minutes, until the vegetables are tender to crisp.
6. Toss in the cooked noodles and the previously stir-fried tempeh. Pour the sauce over the mixture and stir well to combine. Add more seasoning to taste.
7. Finish and serve: garnish with sesame seeds and sliced green onions, and enjoy!
