    Meanwhile, cut steak into 1/4-inch strips; place in small bowl. Stir in remaining 1 tablespoon oil and remaining seasoning mix until combined and coated. Place on pan with vegetables. Bake 7 to 9 minutes longer or until beef is no longer pink and vegetables are tender.

    Heat tortillas as directed on package. Using tongs, transfer steak mixture to serving platter or, if serving on sheet pan, carefully drain excess liquid from pan before serving.

    Spoon steak and veggies onto each tortilla. Serve with remaining ingredients.

Tips from the Betty Crocker Kitchens

  • tip 1
    Feel free to use your favorite bell pepper, and add color by choosing a variety like yellow, red and orange.
  • tip 2
    You may notice some watering out on sheet pan after baking, which is completely normal. Simply pour off the liquid, if desired.
