Using Jarlsberg dip, available in the deli section of many supermarkets, makes this a super-quick appetizer. 

 1 baguette, sliced diagonally into 1/2-inch-thick slices
Jarlsberg dip  
 
Preheat broiler.

Arrange bread on baking sheet. Broil until lightly toasted. Remove from broiler.

Turn bread over. Spread Jarlsberg dip on the untoasted side of each slice. Place under the broiler until the cheese bubbles and starts to brown, about 1 to 2 minutes.

Arrange on platters.
