Even if you don’t have a grill, you can get that same charred, rich flavor using a single cast iron pan. Just a few minutes per side ensures that the outsides get nice and crisp while the inside stays nice and tender. Top the sliced steak with a vibrant raw veggie salad for a restaurant-worthy meal at home!

Before hitting the grill, the steaks sit in a marinade free of soy and gluten. Coconut aminos add a umami taste similar to soy sauce, while chives and garlic lend a savory aroma that only intensifies when it hits the hot grill. Apple cider vinegar adds healthy, zippy acidity and to complement it, honey lends a touch of sweetness. The marinade only needs two hours to tenderize and flavor the steaks, but you can leave them to marinate for up to six hours if you want.

This recipe uses tender flat iron steaks for its rich, fatty marbling. Best of all, it’s a super-affordable cut similar to skirt or flank steak. It is the perfect steak for feeding crowds!

Get started by using a meat mallet to pound the steaks to 1-inch thickness. This will tenderize the steaks and help them cook quicker for the perfect medium-rare sear. Cover the steaks with the marinade and let it sit covered in the fridge for a few hours. Meanwhile, stir together the ingredients for the tomato salad.

When the steaks are ready, preheat the grill (or a cast iron grill pan) over medium-high heat and grease with avocado oil. If you’re using a grill pan, allow it to heat for 4-5 minutes. Drain the marinade and set the steaks right on the hot grill. Cook for 4 minutes on each side for medium-rare doneness.

Let the steaks rest at room temperature for five minutes before slicing, then top with chopped tomato salad and serve!
