- Preheat grill pan or panini press. We improvised at the store. We used a skillet and placed foil on the bottom of a heavy pot to press the sandwich. Brush olive oil or butter on one side of each Bistro Bun. On the other side of each square, spread a thin layer of Sabra Spread. Place buns hummus side up and layer on chicken, provolone cheese, cucumber, roasted peppers, kalamata olives, feta and red onion. Close with top pieces of bread with olive oil or butter sides facing up.
Place sandwich carefully onto hot grill pan butter side down. Grill for about 3-5 minutes, until toasted and grilled on the bottom. Flip and grill for an additional 3-5 minutes. Place a heavy pot or skillet on top of the sandwich to help press it together.
