To make the flavoured oil, place the oil in a saucepan over a medium heat. Smash the garlic cloves using the heel of your hand or the back of a knife (this breaks the clove open to release the flavour). Place the garlic into the oil along with the rosemary and chilli, if using, and season with salt and pepper. Heat until the oil just starts to shimmer, then remove from the heat and set aside for the flavours to infuse.

Chargrill slices of bread in a griddle pan or over hot coals.

Serve the warm toasted bread with the oil and a small pastry brush on the side (or make your own brush by tying some herbs together with a piece of string). Allow guests to brush their own slice of charred bread with flavoured oil and squash ripe, juicy, vine tomatoes on top.

Tip: This makes a really delicious interactive, relaxed starter. You can also add other favourites like Parma ham and a hard cheese like Parmigiano, Manchego or mature cheddar.
