Stir fry is an easy, budget-friendly meal that is perfect for a quick weeknight meal. This recipe calls for a frozen broccoli stir fry mix, but you could use any frozen vegetables you have on hand. Or, use fresh vegetables! Stir fry is great for using up random vegetables in your fridge before they go bad. You could also substitute chicken, pork, or shrimp for the beef, or use tofu for a vegetarian entree. Watch the Stir-Fry Cooking Masterclass Powered by Homemade, brought to you by Davita.
