Preheat oven to 180°C. Grease 8 holes in a 1/2 cup (125ml) capacity muffin tin.
Season the olive oil with salt and pepper.
Using a rolling pin, flatten the bread until very thin and brush with the oil. Carefully push each one into a hole, oiled side up. Bake for 15 minutes until light golden and crisp.
Set aside to cool.
Meanwhile, char grill Vine Sweet Minicaps® baby capsicums in a grill pan or under a medium to hot grill. Set aside to cool, then combine with capers, bocconcini and basil leaves. Season well.
Fill the bread baskets with the mixture.
Combine the remaining oil with the balsamic vinegar and drizzle a little over and around each basket. Serve immediately.
