Slice tempeh into 1/4 inch slices. Combine soy sauce, rice vinegar and 1 tbsp sesame oil. Place tempeh in mixture to marinate. Allow to marinate for at least 10 minutes.
Wash and slice mushrooms. Mince garlic. Put garlic and mushrooms in large pan with 1 tbsp of sesame oil and cook on medium heat for about 10 minutes. Place on side.
Cook tempeh slices on medium-high heat for about 10 minutes. I used a cast iron pan to get that nice golden crust.
Place broth or water in a medium saucepan. Add ramen noodles once boiling and cook for about 5 minutes. Add mushrooms and cook for another minute.
Plate noodles and place your tempeh on top! Garnish with green onion and sesame seeds. Enjoy! :)
