Slice your zucchini into 1/2 inch thick rounds leaving the skin on.
Heat a large skillet over medium-high heat with a touch of oil. Swirl the oil around to lightly coat your skillet.
Add a few zucchini rounds, making sure not to overcrowd the pan.
Cook for about 1-2 minutes on each side until golden brown. Flip and start spreading a teaspoon of sauce onto each zucchini round as shown.
Top with cheese and pepperoni as desired.
Continue to cook for another minute or so, or until the cheese is nice and melty.
Sprinkle lightly with Italian seasoning or freshly chopped basil leaves.
Serve immediately and enjoy!
