After cooking and draining the noodles, Chef Antoine suggests tossing the noodles with a small amount of olive oil to keep them from sticking together.
Store leftover chow mein in an air-tight container kept in the refrigerator for 3-4 days.
Reheat in the microwave until warmed through or in a skillet over medium heat with a pinch of olive oil. When reheating in the microwave, I sometimes add a few drops of water to remoisten the noodles and other ingredients, but it's not completely necessary.
You can add a protein to this dish whether that be chicken, beef, pork, shrimp, and even tofu. I would recommend slicing the protein of choice into thin strips, stir fry style, and browning it in the skillet or wok, then set it aside until all the other ingredients are cooked through. Add the protein back to the skillet at the end.
