Chop cilantro, green onions and place them in a ziplock bag or in a dish. To the greens add soy sauce.
Add beef and squeeze lime juice and orange juice to the mix. Dont get rid of the skins, add them to the marinade. Leave meat to marinade for at least 4 hours.
Grill beef until it's golden brown on both sides and external temperature reads 145 °F.
Serve beef right away. It is delicious when wrapped in tortillas with avocado, tomatoes, salsa or other veggies.
