Heat the oil in a med. skillet over med-high heat. Add vegetables, salt and pepper to taste, and cook, stirring occasionally until desired tenderness and just starting to brown-about 3 min. Remove from skillet and set aside.
To the same skillet, add the steak, salt and pepper to taste, and cook according to package directions. Remove to paper towel.
Assemble the salad-cut the steak into thin strips. Scatter on top of the greens. Add the veggies and any optional toppings. Makes 2 main dish servings or 4 side dish servings.
