To make the spicy Italian salsa: Add the tomatoes, onion, chile pepper, garlic, parsley, basil, olive oil, vinegar, brown sugar, Greek oregano, salt, and pepper to a food processor and pulse until roughly chopped. Cover and refrigerate for 20 minutes.
To make the ricotta and mushroom medallione: Boil the medallione in salt water, once they begin to float, boil for 3 to 5 minutes more, or until al dente. Strain the pasta, dip the medallione in buttermilk and then coat with Italian-seasoned bread crumbs. Fry the medallione in 1/4-inch olive oil heated to 375 degrees F for 1 minute per side, until golden. Strain on a wire rack set over a paper-lined sheet tray. Serve the fried medallione with spicy Italian salsa on the side.
