Pesto sandwiches on a stick with tomato, zucchini, and cheese.
Heat a grill pan over medium heat. Brush zucchini slices with olive oil and season with salt. Place zucchini slices on the grill pan and cook for a couple minutes on each side.
Cut one bread slice into 6 pieces. Do the same with the other slice. Spread pesto on one piece of bread and top with another piece.
Thread the sandwich, cheese, tomato, zucchini, sandwich, and cheese on a skewer. Repeat with the rest of the skewers.
