This recipe is great with frozen or fresh whole green beans. If using frozen, try to get the steam-able in the bag kind, but either way, just warm them in the microwave until they are getting slightly supple. If using fresh, snip off the stems and steam them for about 5 minutes until slightly supple.
A wok works very well for this recipe, but if you don't have a wok, any saute pan will do.
A little char on the green beans is the key to making this dish delicious and special. High heat is a must. Make sure to keep the pan moving because you want to cook these up hot and fast and get some char without burning the beans.
If you don't have dried chili peppers, substitute a couple of tablespoons of red pepper flakes. If you want to leave those out, this will still be a super delicious dish.
