I made a great lunch today. I threw some frozen stir fried veggies into a pan with some onion, soy sauce, and olive oil.
I simmed those for a bit while I cut up some flank steak.
I then removed the veggies and started cooking the steak. Not 3 minutes into the cooking, I poured orange juice over the steak. I let that come to a boil and then I thickened the sauce with a cornstarch/water mix.
Once the steak was cooked through, I threw the veggies back in the pan.
It was quick, easy, and very tasty.
