Preheat your oven to 425°F for roasting the potato.
Dice the red potato into small cubes, toss with half the olive oil, salt, and pepper, and spread on a baking sheet. Roast in the oven for about 20-25 minutes until crisp and tender.
Season the steak with salt, pepper, minced garlic, and chopped rosemary and thyme. Allow to marinate briefly while the potatoes begin roasting.
Heat a skillet over medium-high heat with a drizzle of olive oil. Sear the steak for about 3-4 minutes per side for medium-rare (adjust time according to preferred doneness). Remove and let rest.
In the same skillet, add the summer squash (sliced into half-moons) and sauté over medium heat until just tender, about 4-5 minutes. Season lightly with salt and pepper.
Slice the rested steak against the grain and serve it atop the roasted potato hash with the sautéed summer squash on the side.
Finish with an optional sprinkle of fresh herbs for added aroma and flavor.
