bread soup recipe (homemade)

Last night, I was reading a blog written by an ex-soldier who likes to blog about food matters.  I found him when I was looking for the recipe for the bread soup the French Foreign Legion starved their soldiers on in the early 1900s. I found a number of bread recipes when I went looking for them. Here is once I put together from what I read:

• slightly more than a cup of water
• a cube of beef bullion
• perhaps a tablespoon of dry onion flakes
  
• a slice of sour dough bread

I brought the water, bullion and onion to a boil, then simmers it for about an hour.
I then simmered the bread with the soup.
It actually turned out well.
