Lomo Saltado (Peruvian) - cooking recipe

Ingredients

1 - 1 1/2 lb skirt steaks, petite fillets, hanger or 1 -1 1/2 lb flat iron steak
2 medium red onions, cut in half lengthwise
1 red bell peppers or 1 green bell pepper, cut into strips
1 -2 jalapeno pepper, seeds removed and sliced into strips (optional)
2 garlic cloves, minced
1/4 teaspoon sea salt
4 teaspoons red wine or 4 teaspoons sherry wine vinegar
4 teaspoons soy sauce
4 tablespoons olive oil, divided
1 teaspoon ground cumin
3/4 teaspoon ground black pepper
5 medium yukon gold potatoes, peeled and cut into French-fry like strips
1/2 teaspoon paprika
2 medium tomatoes, cut into wedges
1/4 cup chopped cilantro leaf

Preparation

Place steak in 1 bowl and onions in another. Using a knife, make a paste by combining garlic and 1/4 teaspoon salt. Whisk together garlic paste, vinegar, soy sauce, 2 tablespoons of olive oil, cumin and ground black pepper. Divide marinade between steak and onions. Refrigerate for 1/2 hour.
While steak is marinating, cook potatoes. Drizzle them with 2 tablespoons of olive oil and sprinkle with paprika. Put in a 375 degree oven and roast. Check them after 6 minutes and toss with a spatula. Depending on how thick you cut them, they should cook fairly quickly, so keep an eye on them; set aside.
Before cooking, allow steak and onions to come to room temperature. Place steak on in a hot saute pan with a little oil and cook about 4 minutes per side for medium-rare, depending on which cut you are using. Discard marinade. When done, let steak rest before slicing.
Place onions face down in saute pan and cook until slightly soft, about 6 minutes per side. When done, cut onions into wedges.
In a large bowl combine steak and juices, onions, peppers, tomatoes, cilantro and reserved marinade. Toss gently and adjust seasoning with salt and pepper, if needed. Season potatoes and place on top of meat and vegetables. Serve warm.
