Dice the tomatoes. Remove the seeds from the tomatoes the best you can. Add the tomatoes to a small mixing bowl along with the onion. Add olive oil, salt, pepper, and basil. Mix to combine.

While the tomatoes marinate, turn on the broiler of the oven. Place the ciabatta slices on a baking sheet. Drizzle with olive oil. Toast under the broiler for a few minutes until golden and crisp.

When the bread comes out of the oven, rub the cut side of the garlic clove on the bread.

Cut the burrata carefully into small wedges. Place a small wedge of cheese on each toast slice. Top with tomatoes and fresh basil plus a little more salt and pepper. Serve.
