Put a large sheet pan in the oven, and pre-heat the oven to 425 degrees.
Toss the potato wedges with a few tablespoons of olive oil, as well as salt and pepper. Once the oven has pre-heated, take the hot sheet pan out of the oven, and put the seasoned potatoes on the sheet pan, spreading them out.
Put the potatoes back into the oven, along with an empty sheet pan to pre-heat for the veggies. Roast the potatoes at 425 degrees for 15 minutes, while the empty sheet pan pre-heats.
This is a good time to make your chimichurri sauce if you haven't made it already. You can blend it up and set it aside until serving so the flavors can marry while the rest of dinner is cooking.
Take the potatoes and the empty sheet pan out of the oven. Stir the potatoes around and return them to the oven. Toss the veggies in a couple tablespoons of olive oil, as well as salt and pepper, and spread them out on the pre-heated empty sheet pan. Roast the potatoes sheet pan & veggie sheet pan for 15 minutes.
Stir the veggies and potatoes around, and return to the oven for a final 10 minutes while you prepare the steak.
Pre-heat your grill pan or grill until very hot. I let my grill pan heat over high for a good 7 minutes before placing steaks on the grill.
Pat dry your steak with a paper towel. Rub each steak with olive oil, and generously sprinkle with sea salt, and then pepper.
Grill your steaks on a hot grill pan for about 4 minutes on each side for medium rare, depending on the thickness of your steaks. You can cook longer if you would like more doneness.
Let the steaks rest for 5 minutes before slicing. You can pile your steak bowls with the roasted potatoes, veggies, and sliced steak, and then drizzle the chimichurri to your liking.
