Slice the focaccia round in half through the middle to create 2 rounds. Place cut-side up on a baking sheet. Brush the bread with the olive oil and season with a pinch of salt and pepper.
Spoon 1/4 cup of the marinara over each round and sprinkle the provolone over the top, making sure to leave the outer edge of the focaccia rounds exposed. Over the cheese, distribute the sausage slices, hot cherry peppers, kalamata olives, artichokes and Manzanilla olives across each round.
Bake until the edges are golden and the cheese is melted, 10 to 12 minutes. Dot or drizzle the pizzas with the pesto and sprinkle with the Parmesan and basil. Slice and serve.
