Pat the steak dry using paper towels and season generously with salt and pepper.

Heat olive oil in a skillet over medium-high heat, add the steak in a single layer without overcrowding.

Cook for 2-3 minutes until seared, then flip and cook for another 2-3 minutes. Transfer to a plate once browned.

Lower heat to medium-low, melt the butter in the same skillet, then add minced garlic and cook for about 30 seconds until fragrant.

Return the steak bites to the pan and stir well to coat with the garlic butter.

Sprinkle chopped parsley over the steak bites and serve immediately.
