Step 1

Whisk together the olive oil, soy sauce, vinegar, garlic, cumin and salt and pepper in a large bowl.

Step 2

Slice the steak into bite sized pieces and set into the bowl. Mix and marinate for at least 10 minutes. Set aside.

Step 3

Cover the potatoes in a large bowl with cold water and let them soak for at least 10 minutes (this will help with crispiness).

Step 4

Heat the olive oil in a large pan or wok to medium-high heat.

Step 5

Season the sliced potato with salt and pepper, then cook for 10-15 minutes, or until cooked through to your liking. SEE NOTES.

Step 6

Set the potatoes aside.

Step 7

Heat 1 tablespoon olive oil in the same pan or wok over medium-high heat.

Step 8

Add the onion and peppers and stir fry for 2 minutes to soften.

Step 9

Drain the marinade from the steak but keep the marinade. Stir fry the steak with the onion and peppers 3-4 minutes, until the steak forms a nice crust.

Step 10

Add the stir fry marinade and tomato and stir fry for 1 minute.

Step 11

Add the cooked potatoes/French fries along with the cilantro and hot sauce, if desired. Stir fry to heat through.
