Flatten the cubed steaks by placing them between sheets of plastic wrap or waxed paper and pounding with the flat side of a meat mallet or a rolling pin. Don't have a meat mallet or rolling pin? Press the heel of your hand over the top of the steak until it is evenly flattened.
Traditional pesto is a mixture of basil, garlic, olive oil and pine nuts. Today, however, this popular sauce can be made from other herbs and vegetables instead of basil. There is sun-dried tomato, roasted bell pepper and spinach pesto, just to mention a few, so use whichever pesto you like.
To add crunch and bright red color to this dish, add a chopped small red bell pepper to the sauce when you stir in the cornstarch mixture.
