Juice and zest of 3 limes
Juice and zest of 2 oranges
2/3 cup extra virgin olive oil
7 cloves minced garlic
1/4 cup diced onion
2 teaspoons dried oregano
2 teaspoons ground cumin
1 teaspoon sea salt
Freshly ground black pepper
4 (4-ounce) flat iron steaks or any similar thin 1/2inch steak)
1 tablespoon vegetable oil
Whisk together lime juice and zest, orange juice and zest, olive oil, garlic, onion, oregano, cumin and salt and pepper in a bowl. Reserve 1/2 cup marinade to drizzle over grilled steaks.
Place steaks in marinade, cover and refrigerate for at least one hour, up to overnight.
Preheat grill or grill pan to medium high heat. If you can only keep your hand over the heat for 2 to 3 seconds, it’s hot enough! Brush grill lightly with vegetable oil. Place steaks on grill and grill 4 to 5 minutes per side for medium rare.
Remove steaks from the grill, drizzle with reserved marinade, cover loosely with foil and allow to rest 10 minutes.
Notes: Recommend 12 hour marinade, turn every hour or 3.
