Absolutely! Vegetable Lo Mein can be made ahead and reheated. Just keep in mind that the noodles may absorb some of the sauce, so it might not be as saucy as when freshly made. When reheating, you might want to add a splash of water or a little extra soy sauce to freshen it up. It's great for meal prep and can be stored in the fridge for 3-4 days.
