1. Pour the tomatoes into a medium bowl and using hands, squeeze each tomato through your fingers to break it up into small pieces (be careful, they can squirt). Set aside. 2. Heat olive oil and butter in a large saucepan over medium-high heat until butter is melted. If using pancetta, add to pan and cook, stirring constantly until fragrant, about 2 minutes. Reduce heat to medium and add onion, garlic, oregano, and red pepper flakes. Cook, stirring constantly until fragrant and softened but not browned, about 3 minutes. Add tomatoes and their juice, chicken broth, kidney beans, and bay leaves. Bring to a boil over high heat then reduce to a bare simmer. Cook for 20 minutes, adding pasta to soup for the last 5 to 10 minutes (depending on the package directions). Season to taste with salt and pepper. Discard bay leaves, stir in parsley and serve, drizzling each serving with extra-virgin olive oil at the table.
