Arrange zucchini slices on a parchment lined baking sheet. Drizzle zucchinis with olive oil and season with salt and pepper. Broil zucchinis for 5 minutes.
Remove zucchini slices from oven and top with pizza sauce, mozzarella, feta, and oregano. (Or add more toppings! Bacon bits would be perfect.)
Broil for 4 more minutes, or until cheese is lightly browned. Top with grated parmesan.
