Wash and slice your green onions.
Grate your garlic and slice your lemon.
In a pan on medium heat, add 2 tablespoons oil. Then, add your green onions and grated garlic. Saute for 2-3 minutes until the green onions have wilted.
Place your green onion sauce in a bowl, then add some salt, yuzu chili paste, lemon juice, sugar and sesame oil. Mix together and set aside.
Use the same pan that you saute your green onions. The leftover oil has a lot of flavor! Turn heat to medium. Add your sliced beef and saute for 3-5 minutes.
After cooking your beef, season with some salt and pepper to taste.
To serve, add the green onion sauce on top of the beef. Enjoy with rice or lettuce wraps!
