Step #1
Skin the tomatoes by cutting a shallow cross into the bottom of each, then plunge them into boiling water for about 30 seconds.Carefully transfer them into a bowl of iced water so the skins peel off easily.
Step #2
Cut each tomato into quarters, scoop out the seeds and place into a sieve over a bowl. Press the seeds and pulp through the sieve to release the juice into a bowl. Put the tomato quarters into a separate bowl.
Step #3
Cut each of the skinned red and yellow peppers into eight pieces and add to the tomato quarters. Add the chilli, capers and olives.
Step #4
Tear the Ciabatta into large chunks and place into a separate bowl.
Step #5
Add the vinegar, garlic and oil to the sieved tomato juice. Season, to taste, with salt and freshly ground black pepper and whisk well to combine the flavours together.
Step #6
Throw over the beans with the chopped avocado and add the asparagus before garnishing with the fresh basil leaves.
