- Steak - Baking Soda - Water - Oil - Bell Pepper
In a large bowl, toss the steak slices with baking soda and water and let sit for 15 minutes. This is called "velveting" and will tenderize the meat.
Place in a colander and rinse thoroughly with water. Then, place them on paper towels and pat dry. Be sure to get the beef really dry so it gets a good sear!
Stir-fry the bell peppers and onion until tender, about 5 minutes. Set aside on a plate.
Add beef to the skillet in a single layer (cook in batches if needed), and cook for about 1 minute unmoved, to get a nice sear on it.
