Roast the Carrots: Preheat oven to 425°F. Toss carrots with olive oil, thyme, oregano, salt, and pepper. Spread on a lined tray and roast for 20–30 minutes, tossing halfway, until tender and caramelized. Finish with fresh parsley.
Make the Chimichurri: In a bowl, mix parsley, red onion, garlic, olive oil, red wine vinegar, water, salt, pepper, red pepper flakes, and optional oregano. Let sit while preparing the rest.
Cook the Steak: Lightly spray steak with oil and season with garlic powder, cumin, oregano, salt, and black pepper. Grill or sear over high heat for about 4 minutes per side for medium-rare or to desired doneness. Rest 5–10 minutes, then slice thinly against the grain.
Cook the Broccoli: Steam or microwave broccoli until bright green and just tender. Season lightly with salt.
Assemble the Plate: Plate sliced steak, drizzle generously with chimichurri, and serve with roasted carrots and broccoli on the side.
