Cut the thin sliced steak into 2" pieces, and place them onto the baking tray
Set the oven to 170F. Put the steak into the oven. After 5-6 mins, take out the tray, and flip the steak. Bake for another 3-4 mins or until the steaks turn from red to pink.
Cut the jalapeno into 0.5"-wide pieces
Put the frying pan on top of the stove. Add oil and turn heat to high. Add the jalapeno. Saute at medium to high heat.
Once both sides of the jalapeno pieces are slightly charred, add the baked (cooked) steak to the pan. Keep heat at medium to high
Keep stirring to make sure all steak pieces are sauteed.
Once fat in the steak renders out, and the steak turns brown, add salt and ground black pepper. Stir and mix for 2-3 mins
Serve it immediately when cooking is done

Notes
I kept ingredients simple. You could use other seasonings to make Philly steak, fajitas or Oriental style.
If you want the dish to be more spicy, you could keep the pith and seeds.
You can bake the steaks at higher temperature for a shorter time. The key is trying not to render out the moisture.
