Pat the steak dry with paper towels and season generously with salt and pepper. Let sit for 5 minutes.

Heat a large skillet over medium-high heat and add olive oil. Sear the steak bites for 1-2 minutes on each side until golden.

Lower heat and add butter to the skillet. Once melted, add minced garlic and sauté for 30 seconds.

Toss in the zucchini and sauté for 3-5 minutes until tender-crisp.

Return the steak to the skillet and toss with the zucchini, simmer for another 1-2 minutes.

Remove from heat, transfer to a platter, and garnish with chopped parsley before serving.
