Firstly, make a vinaigrette by whisking together the olive oil, white wine vinegar and Schwartz for Chef Arrabbiata Seasoning. Mix this with the chopped tomatoes and red onion.
Slice each ciabatta in half and then cut into 10 large slices. Grill until golden brown.
Top each slice of bread with the tomato mixture and garnish with the Schwartz for Chef Premium basil.
