Slice the chicken breast into thin strips.
Trim the ends of the green beans.
Mince the garlic.
In a large skillet over medium heat, add the olive oil.
Once the skillet is hot, add the minced garlic and cook for about 30 seconds, or until fragrant.
Add the chicken strips to the skillet and cook for 6–8 minutes, turning occasionally, until browned and fully cooked.
Add the trimmed green beans and mix thoroughly.
Add soy sauce and stir to coat evenly.
Cook for an additional 5–7 minutes, until the green beans are tender yet crisp.
Season with black pepper and red pepper flakes, if desired.
Add a splash of lemon juice for brightness.
Serve hot, straight from the pan.
