Combine all ingredients into a large mason or bowl if you prefer. Leave to marinate in the fridge for at least one hour up to one day.
Serve in a large bowl with fresh bread. Or use to make crostini with halved cherry tomatoes and fresh basil. They make a great canapé if you pop them on a cocktail stick with a some cherry tomato halves and fresh basil. I also love these in a simple tomato salad - they’re so delicious!
