Season steaks with salt, garlic salt, and black pepper mixture.
Get your grill or BBQ up nice and hot (but not over 600° on the BBQ thermometer)
Generously brush cooking oil over the grates of your grill. Then instantly place steaks at a 45° angle on the grill. After 2-3 minutes rotate the steaks 90°. Wait again for 2-3 minutes and flip your steaks over, repeating the same process to create those nice cross-hatch grill lines.
Once the internal temperature of the steak reaches 130°, remove and let stand for 3 to 4 minutes, allowing the meat to reach an internal temperature of 135 degrees – a perfect medium rare.
