Marinate the Steak. In a bowl, toss the steak strips with olive oil, salt, and pepper. Allow them to marinate for at least 15 minutes to absorb the flavors.
Preheat the Grill. Get your grill or grill pan hot and ready for cooking.
Grill the Steak Strips. Cook the marinated steak strips on the hot grill for 2-3 minutes per side or until they reach your desired level of doneness. Remove from the grill and let them rest.
Prepare the Greens. In a large salad bowl, combine the mixed greens, cherry tomatoes, sliced red onion, cucumber, and carrots.
Add Steak. Place the grilled steak strips on top of the salad.
Drizzle with Vinaigrette. In a small bowl, whisk together balsamic vinaigrette, olive oil, salt, and pepper. Drizzle the dressing over the salad.
Toss Gently. Toss the salad gently to ensure all ingredients are coated with the dressing.
Serve and Enjoy. Plate the salad, ensuring each serving has a good mix of steak and veggies.
