Add olive oil, oregano, salt and pepper in a bowl. Heat in microwave on high for 40 seconds. Remove and add butter. Stir and set aside.
Using kitchen scissors, cut pita pockets into 4 pizza slice shaped wedges (slice in half, then slice each half again to make the wedges). Cut again along curved outer edge to separate into two. Brush both sides of the pita wedges with warm olive oil mixture.

Place wedges crust side down on a baking sheet. Spread 1 tsp of salsa to top each wedge. Cut provolone slices into 4 wedge shapes and place one on top of each. Top with a slice of pepperoni, if desired. Drizzle with any remaining olive oil and sprinkle lightly with coarse sea salt.

Bake in a preheated 375°F oven for 15 minutes or until golden brown and cheese is bubbly. Serve while still warm.

Makes 16 wedges.
