Add breakfast sausage, chopped shallots, and mushrooms (optional) to a wok or large pan, and saute until the sausage is cooked, and shallots are translucent.
Toss in the spinach or baby pac choi. Saute just until greens darken and wilt - about 2 minutes.
Add ¾ cup of water, the Hot & Spicy Fortune Yakisoba noodles, and the included spice packet. Stir-fry for 1-2 minutes, until noodles relax and sauce base is thoroughly incorporated.
With the back of a spoon, make two indentations in the stir-fry mixture. Carefully break an egg into each indentation, then immediately cover the pan.
Cook for one minute, then remove from heat and allow to sit covered until egg whites are fully cooked, but yolk is still runny, about 3-5 minutes. (It's ok to quickly peek and check for done-ness.)
Dish and serve!
