In a large mixing bowl add basic raw tomato sauce, cucumber, fennel and cubed bread. Toss to mix. Pour olive oil and vinegar over the mixture and toss again. Add capers, red onion and bell pepper, toss once again. The entire process takes no more than 5 minutes. The panzanella may be served immediately or an hour later. As time passes the salad becomes softer in texture. Yield: 4 servings
