Heat EVOO in a large frying pan over medium-low heat. Add eggplant and cook for 5-8 minutes, tossing constantly, until the eggplant is glossy. Add the capsicum, tomatoes and 1 cup water and cook for 15-18 minutes, stirring occasionally, until the mixture just starts to break down.
Stir in capers, olives, vinegar and freshly cracked black pepper to taste. Simmer gently, stirring occasionally, for 8-10 minutes until the vegetables are very tender and the caponata is thick and stew like. Stir through pine nuts and fresh herbs.
Store the caponata in an airtight container in the fridge covered with EVOO.
