Preheat your oven to 450°F. Spray a rimmed baking dish with olive oil spray. I use a 10 X 7-inch ceramic baking dish from Sur La Table.
Place the chicken breasts in the baking dish, flat side up. Lightly spray them with olive oil. Sprinkle them with kosher salt, black pepper, garlic powder, and oregano. Bake for 15 minutes.
Remove the baking dish from the oven. Turn the chicken breasts. At this point, you can lightly spray them with more oil and sprinkle with a bit more salt and pepper, but it’s optional. Top the chicken evenly with pizza sauce, shredded mozzarella, pepperoni, and olives.
Return the baking dish to the oven. Bake until the chicken is cooked through (its internal temperature should reach 165ºF) and the cheese is melted, about 15 more minutes. Garnish with chopped basil and serve.

Notes
*When buying chicken breasts, try to pick ones that weigh no more than 8 ounces each. So if you buy them in trays, pick the trays that weigh 1 lb. rather than those that weigh 1.5 lb. The latter ones are too big for this recipe. The basil is really important. It adds amazing flavor and really elevates this dish. I would go as far as saying that if you don't have fresh basil on hand, you shouldn't make this recipe.You can keep the leftovers in the fridge, in a sealed container, for up to 4 days. Reheat them very gently, in the microwave at 50% power.
