Preheat your oven to 425°F.
Cut the sweet potato into 1/2-inch cubes, toss with a drizzle of olive oil, salt, and pepper, and spread evenly on a baking sheet.
Roast the sweet potatoes in the oven for 20-25 minutes or until crispy and tender, stirring halfway through.
Meanwhile, pat the steak dry with paper towels. Season both sides generously with salt, pepper, minced garlic, and chopped fresh herbs.
Heat a skillet over medium-high heat and add olive oil. Once shimmering, place the steak in the pan.
Sear the steak for about 3-4 minutes on each side for medium-rare (adjust time to desired doneness).
While the steak is resting for a few minutes, steam or quickly sauté the green beans in a separate pan with a pinch of salt until they are bright green and slightly tender.
Slice the steak against the grain and arrange on a plate with the roasted sweet potatoes and green beans.
Serve immediately and enjoy your balanced, flavorful meal.
