Lo mein noodles are Asian wheat noodles, similar to spaghetti. You can find them in the Asian foods aisle of the supermarket, or substitute spaghetti or angel hair pasta.
Bok choy has white stalks similar to celery, but topped with deep green leaves. If available, baby bok choy is more tender with a mild cabbage flavor.
Feel free to change up the vegetables in this stir-fry based on what’s available. Thinly sliced carrots can be added at the same time as the bok choy stems, and bell peppers can be added with the snow peas. When planning a stir-fry, choose vegetables based on colors and flavors.
