Step 1

Place the diced onion into a small bowl along with 1-2 ice cubes and cold water. Leave to one side. (Optional, but recommended)

Step 2

Slice your chosen tomatoes. Either halve or quarter cherry tomatoes. Remove the hard white/green core top in larger tomatoes and cut into chunks. Place them all into a large mixing bowl.

Step 3

To make the dressing, mix together the mustard, vinegar, oil, honey, salt and black pepper in a small bowl.

Step 4

Drain the onions and add them to the tomatoes. Pour over the dressing and give it all a thorough mix.

Step 5

Tear in some fresh basil leaves and mix through. You could also add a few mozzarella pearls if you like (optional).
