This is one of my husband's favorite soups I make. It is very simple and cheap - that's my husband cheap and easy!!
6 large onions, slice thin
1 cup butter (not margarine)
14 beef bouillon cubes or 14 tsp of the loose bouillon
8 cups of water
2 tsp Worcestershire sauce
1 tsp salt
In large skillet saute onions in butter until limp. Transfer onions and butter to a large pot. Add water, bouillon, Worcestershire sauce and salt. Cover and simmer on low 4 to 6 hours. Serve in individual bowls with a slice mozzarella cheese. Put under broiler for cheese to melt. I also like to serve with crunchy, warm french bread.
Note: If you are short on time you can simmer for two hours - I have done this and it still tasted great.
