Preheat a frying pan over high heat with a little oil. Add in the french fries and sauté them to brown on most sides. Remove to a paper towel lined plate.
Add a little more oil to the pan and add in the steak. Cook about 2 minutes to brown on all sides. Remove to another plate.
Add the onion, tomato, and jalapeno to the pan and cook about 5 minutes to char a bit on the edges. Add in the garlic and ginger and cook 1 more minute.
Add in the tamari and vinegar and stir to cook. Add the meat back to the pan and stir to combine.
Finally, add the french fries back to the pan and stir.
Serve and garnish with the cilantro.
NOTE - Aji Amarillo peppers are more authentic in this dish but often hard to find, if you can find them, use in place of the jalapenos
