Cut one end off of the zucchini. Slice on a mandolin set to 3/16”. Lay the slices on a few paper towels and sprinkle with salt. Allow to sit for 5-10 minutes. Wipe the slices with a paper towel to remove excess moisture and salt.
Lay the zucchini on a sheet pan lined with parchment paper in a single layer.
Top with 1-2 teaspoons of sauce. You want to cover most of the zucchini but in a thin layer.
Sprinkle with mozzarella cheese, parmesan cheese, and Italian seasoning.
Add additional toppings if desired.
Bake at 400F for 10 minutes. Serve with fresh basil or parsley.
Store leftover zucchini pizza bites in an air tight container kept in the refrigerator for 3-4 days.
