Add 1 tablespoon oil to the wok. This could be peanut oil, canola oil, sunflower oil, or any neutral oil.
Add the ginger and garlic to the pan, and stir around for a few seconds.
Add the green beans and cook, stirring, for about 3 minutes or until the green beans are crisp, tender and bright green. The skin will also start to blister, which is what we want.
Add the soy sauce, chili paste, maple syrup, and sesame oil, and stir fry until the green beans are coated, and the sauce starts to look sticky. You’re basically making homemade sweet chili sauce right in the wok.
Toss in the chopped peanuts and toss for another few seconds until they get coated in the sauce too.
