This stir-fry uses julienned potatoes instead of sweet potato glass noodles, brought together with deep savory flavor from oyster sauce. It comes together easily with leftover vegetables and ham, making it a great dinner side dish. The key is to stir-fry only until the potatoes are cooked through so the vegetables do not turn mushy.

Steps
I thinly julienned 1 medium potato, soaked it in water to remove the starch, and drained it.
I julienned 5 slices of ham left over from making spaghetti; sausage or any other ham is fine too.
Julienne the onion and carrot, shake out the seeds from the green chili peppers and cut to match the length, and thinly slice the button mushrooms.
I used button mushrooms because I had them, but shiitake mushrooms, king oyster mushrooms, oyster mushrooms... really any vegetables are great.
Heat oil in a frying pan and stir-fry the potato briefly.
Add the carrot and stir-fry briefly.
Add all remaining vegetables except the ham and stir-fry briefly. Then,
Add the ham at the very end.
After adding the ham, add the oyster sauce, salt, ground black pepper, and toasted sesame oil, then toss evenly.
If you stir-fry too long the vegetables will turn mushy, so just cook until the potatoes are done.

FAQ
Why do I need to remove the starch from the potatoes?
It is recommended to soak the julienned potatoes in water to remove excess starch, then drain well before cooking.
Can I season this with something other than oyster sauce?
If you want a cleaner look and lighter color, you can season with salt alone instead of oyster sauce.
Can I substitute other ingredients for the sliced ham or button mushrooms?
You can use sausage or any other type of ham, and for mushrooms, you can substitute various vegetables from your fridge like shiitake mushrooms, king oyster mushrooms, or oyster mushrooms.
Is there a trick to keeping the vegetables crisp while stir-frying?
Stir-frying the vegetables for too long will make them mushy, so it is best to stir-fry them gently just until the potatoes are cooked through.
