For the olive spread: Combine the Kalamata and Manzanilla olives, red pepper, olive oil, vinegar, parsley and oregano in a food processor. Pulse 8 to 10 times, until evenly incorporated but still chunky (nothing larger than pea-size). If not using immediately, transfer the spread to an airtight container and refrigerate for up to 4 days. (Makes 2 cups.)
For the bruschetta: Lay the baguette slices on two baking sheets. Top each slice with 1 teaspoon of the olive spread. Then layer the slices with a piece of mozzarella, followed a piece each of provolone, mortadella, capicola and salami. (At this point, the bruschetta can be stored in the refrigerator for up to 4 hours; remove from the fridge 30 minutes prior to serving.) Finish the bruschetta with a small dollop of olive spread, and garnish with a basil leaf. Serve immediately.
