Sliced steak over greens with blue cheese crumbles makes your lunch feel like a steakhouse experience. High protein, surprisingly quick to throw together.
Remove the steak from the refrigerator 15 minutes before cooking; season both sides evenly with salt, black pepper, and garlic powder.
Preheat a grill pan or outdoor grill to high heat. Brush the steak lightly with 1 tablespoon of olive oil.
Grill steak for 3–4 minutes per side (medium-rare), or adjust timing for your preferred doneness. Let the steak rest for at least 5 minutes on a cutting board to retain juices.
While the steak rests, combine the mixed greens, cherry tomatoes, and red onion in a large salad bowl.
In a small bowl, whisk together 1 tablespoon olive oil and balsamic vinegar for the dressing.
Slice the rested steak thinly across the grain. Layer slices over the greens; top with blue cheese crumbles and avocado. Drizzle with dressing right before serving.
