1. In a large bowl, combine tomatoes, olives, artichokes, cucumber, onion, capers, basil and croutons.
2. In a small bowl, whisk together vinegar, salt, garlic, mustard, olive oil and pepper.
3. Toss with salad and serve. This salad can be prepared a day in advance. The croutons will become softer, like bread. For crunchy croutons, add right before serving.
