I use the George Foreman grill to get nice grill marks on the hot sandwich.
2 slices Italian bread
3 pieces salami
mozzarrela or provolone
Kale pesto
Spray outside of bread with oil. Slather pesto on inside of one piece. Top with cheese. Top with salami. Cover with last piece of bread, oil side out. Place in grill and press down to get grill marks. Cook until bread toasted and cheese melted.
