Preheat your oven to 425°F.
Wash and scrub the potato thoroughly. Cut it into small cubes to ensure a crispy exterior when roasted.
Toss the potato cubes with half of the olive oil, salt, black pepper, and a little bit of the fresh herb mix. Spread them out on a baking sheet and roast for 20-25 minutes until golden and crispy, stirring halfway through.
While the potatoes roast, pat the steak dry with paper towels. Mince the garlic and chop the remaining herbs.
Season the steak generously with salt, black pepper, minced garlic, and chopped herbs.
Heat a skillet over medium-high heat. Add the remaining olive oil and sear the steak for about 3-4 minutes per side for medium-rare, adjusting the time based on your desired doneness.
While the steak rests for a few minutes after cooking, steam or lightly sauté the green beans until they are tender-crisp.
Slice the steak against the grain and plate it alongside the roasted potatoes and green beans. Garnish with extra herbs if desired.
Serve warm and enjoy a balanced meal of lean protein and nutrient-rich vegetables.
