Stir fry probably is what my son requests the most often for dinner, so I make it often. I like coming up with various combinations/seasonings. This one is a keeper. Just the right amount of heat for us without being "burny." My son told me I needed to post how I made the stir fry tonight, so that is what I am doing. :) (The pic shows garlicky chicken and broccoli also, as I make a LOT of food.) Enjoy!
I like to have all my veggies chopped the night before or morning of to make it easy when I get home from work. Heat your wok or large fry pan to high. Add enough canola oil to cover bottom and add a splash of sesame oil. As this is heating....
Whisk together the sauce (I just use a fork): sesame oil, soy, rice vinegar, chili garlic paste, and cornstarch. Make sure there are no cornstarch lumps. Set aside.
Add your steak slices, onions and peppers to the pan. (I keep them separate for ease of flipping the steak pieces). Salt the peppers & onions lightly. When bottom of steak gets seared, toss to other side. Toss the onions & peppers frequently for a minute or two. As they get soft, add the mushrooms and toss. Then add the tomatoes, and toss everything together.
Add beef broth a little at a time until you feel it is the right amount of liquid. Simmer for a minute or two, then add the soy mixture sauce. Add a generous amount of fresh ground black pepper. Add salt to your liking -- I don't need any.
Coat evenly and once it all is covered & hot -- you are ready to dig in with a bowl of rice. Enjoy!
