The best way to figure quantities on bread is to measure how long it is.  Plan on about 1 1/2 inches per person.  

Ingredients:  

• 1 loaf of soft french bread (about 1 lb)
• 1 packet Onion Soup Mix
• 8 Tab. softened butter (1 cube)

Directions:

1. Preheat oven 350°.
2. Slice the load of bread lengthwise.
3. Spread each half with softened butter.
4. Sprinkle the dry soup mix over the bread.
5. Place in preheated oven until bread is slightly toasted and butter has melted.
6. Remove bread and allow it to cool slightly before cutting into pieces.

Serves: 6-8
