Cut ciabatta into 3/4 inch slices and grill on a grill pan or toast in the oven at 350°F. for 10 minutes.
Cut halloumi in 1/4 inch slices. In a frying pan on medium heat, drizzle olive oil and place the cheese onto the pan. Fry for a few minutes until soft and slightly golden brown. Turn over and fry until golden brown on the other side.
Place the halloumi on the crostini and top with a spoonful of muffuletta.
Place a basil leaf on top for garnish.
Notes
My favourite muffuletta is from Longos. You can find it in a jar in most grocery stores and definitely online.
