In a bowl, combine zucchini slices, olive oil, vinegar, Italian seasoning, salt, and pepper. Toss to coat.
Refrigerate for at least 1 hour before serving.
Serve cold or at room temperature.
Notes
Chef's Tip: Slice the zucchini paper-thin - thin slices marinate through fully in the hour of chilling; thicker ones stay raw-tasting at the core. Keto Swap: none needed - naturally keto.
