New Years 2 dish special - sweet and sour potato strings and pepper steak

Today, we make two really simple dishes with ingredients easily found in any grocery store.
For the potatoes, you can easily forego the szechuan peppercorns and chilis. That's actually the version I grew up with. For the sauce, start with 1tsp of soy sauce, 2tsp of chinese vinegar, 2tsp of sugar per potato. Adjust amounts based on your own preferences - it's honestly hard to go wrong. As always, salt to taste (~1tsp to start)
