Toss sirloin steak with soy sauce, red wine vinegar, ground cumin and salt.

Heat half of vegetable oil in a wok or large skillet until smoking. Sear marinated beef in two batches for about 2 minutes each, then set aside.

In the same pan, stir-fry red onion, garlic, aji amarillo and tomatoes for 2 to 3 minutes, keeping the vegetables a little crisp.

Return seared beef to the pan with stir-fried vegetables and toss for 1 minute. Scatter cilantro on top.
