Why not try this? I like to think of it as a grilled cheese sandwich to the 10th power.

Ingredients

• 8 slice(s) rye bread
• 4 teaspoon(s) sharp, hot mustard
• 1/2 head(s) (small) radicchio, thinly sliced
• 1/2 tablespoon(s) balsamic vinegar
• 1/4 pound(s) hard salami, thinly sliced
• 1/2 pound(s) Jarlsberg cheese, thinly sliced
• 4 teaspoon(s) butter, melted

Directions

1. Spread 4 slices of bread with mustard.
2. Toss the radicchio with the vinegar, place on top of the mustard-spread slices of bread. Layer each sandwich with 3 slices of salami and 3 slices of cheese. Top with the remaining bread. Brush both sides of the sandwich with butter. Grill in a panini press until cheese is melted — about 4 minutes. Serve immediately.
