Preheat grill to medium-high; if using a charcoal grill it will be hot enough when you can hold your hand over the heat for 3-4 seconds.

Mix the butter, jalapeno, and garlic in a small bowl, set aside.

Season each side of the steak with salt and pepper.

Cook over the hottest section of your grill; flip one time, until it is browned. This will be about 3 minutes per side.

Place meat over the cooler part of your grill and cook 8-9 minutes per side, flipping one time.

Take off grill and let meat sit for about 10 minutes.

Serve with butter mixture.
