Everyday Food editor Sarah Carey makes a healthy, hearty dinner using some of the best produce late summer has to offer. She also gives tips on how to cook your beets faster and shows you how to avoid overcooking your chard.
Preheat oven to 400 degrees. Place beets on a large sheet of foil; drizzle with 1 tablespoon oil and season with salt and pepper. Fold foil to make a packet and crimp edges to create a tight seal. Place on a rimmed baking sheet and roast until beets are tender, 25 to 30 minutes.
Meanwhile, in a large skillet, heat 1 tablespoon oil over medium-high. Season steaks with salt and pepper and cook until medium-rare, 3 to 6 minutes per side (depending on thickness). Transfer to a plate to rest.
Wipe skillet clean with a paper towel; return to stove. Heat 1 tablespoon oil over medium-high. Add Swiss chard; cook, stirring constantly, until wilted, about 2 minutes. Add beets and vinegar; season with salt and pepper and toss to combine. Thinly slice steak against the grain and serve with beets and greens.
