Step 1

Cut the steak into bite size cubes about 3/4-inch.

Step 2

In a small mixing bowl, whisk together the teriyaki, brown sugar, corn starch, sesame seed oil, garlic powder, garlic salt and red pepper flakes. Whisk until the brown sugar and corn starch are completely dissolved.

Step 3

Pour over the steak bites and toss until evenly coated.

Step 4

Drizzle a large skillet (12-inch) with olive oil. Turn to high heat.

Step 5

Once the pan is hot, fry the steak bites in batches. (Lower the heat to medium-high if needed to prevent burning) Cook for 4-6 minutes total on both sides turning as needed. Adjust the cooking time to your desired doneness.

Step 6

Remove to a platter and keep warm until all of the steak bites are cooked. Add additional olive oil between batches as needed.

Step 7

Add the green pepper and onion to the skillet. Saute for 2-3 minutes over medium-high or until crisp tender. Adjust the salt, if needed. (The drippings left behind in the pan will season the vegetables)

Step 8

Add the steak bites back to the skillet and stir to distribute.

Step 9

Remove the skillet from the heat and serve.
