Preheat the Blackstone griddle over high heat (approximately 450 degrees F). You want the griddle to be hot to get a good sear on the steaks.

Thinly slice the steak. Then chop into bite site pieces.

Spread the oil out onto the Blackstone grill.

Once the oil is hot, place the sliced steak on the Blackstone grill on top of the oil. Season the steak with salt and pepper. Let them cook for 2-3 minutes and do not move them to get a good sear on the steak.

Use a spatula to flip the steaks onto a separate section of the grill. Then cook the steaks for 2-3 more minutes to sear the opposite side of the steaks.

Then top the steak with 2 Tbsp of the butter and allow it to melt into the steak mixture.

Remove the steak from the grill to a separate plate. Top with the fresh lime juice and set aside.

Melt the remaining butter on the Blackstone grill and place the tortillas in a single layer on the grill. Cook the tortillas for 2-3 minutes per side until browned.

Then it's time to assemble the tacos. Use 2 tortillas per taco. Spoon the meat mixture onto the tacos. Then top with the cilantro and diced onions.

Serve warm and enjoy!
