1. Preheat an outdoor grill or indoor grill pan to a medium-high heat. Lightly oil the grill grates.
2. Generously season the steaks with salt and pepper, then rub with garlic powder and chopped fresh thyme. Place on the grill and cook to your desired doneness, about 5 minutes per side for medium-rare. Transfer to a cutting board.
3. Allow the steak to rest for at least 5 minutes, then thinly slice opposite of the grain. Evenly distribute the arugula among 4 plates. Top with an even amount of peach slices and red onion, followed by the steak, and sprinkle on the feta and almonds. Drizzle with the balsamic vinegar and season with salt and pepper. Serve immediately.
