Arugula Steak Salad

0 Preheat oven to 400°F.

2 Season steak generously on both sides with salt and pepper. Let it rest at room temperature to take some of the chill off.

4 Drain pickled red onions. 
5 Assemble salad with a bed of greens topped with avocados, red onions, tomatoes, and warm potatoes.
6 Thinly slice steak and arrange it on top of the salad. Crumble blue cheese over top. Drizzle with vinaigrette until dressed to your liking.
