Preheat your oven to 400°F (200°C).

Slice the large focaccia bread horizontally to create two equal halves.

Drizzle extra virgin olive oil on the inside of both focaccia halves, followed by salt and pepper.

Place the bottom half of the focaccia on a baking sheet and tear the burrata cheese into portions, distributing it across the bottom.

Arrange the heirloom tomato slices over the burrata generously.

Sprinkle the fresh basil leaves over the tomatoes.

Drizzle balsamic glaze over the layered ingredients.

Place the top half of the focaccia over the assembled ingredients and press down gently.

Optionally, place in the oven for 5–10 minutes until the focaccia is golden and fragrant.

Slice the sandwich into manageable portions and serve immediately.
