    Charlotte (via Laura),

    Thanks Much. I will try this tomorrow. This looks doable. For the longest time, my daughter has been begging for French Onion Soup but almost all recipes are just too darn labor intensive for my lifestyle (single father of three with full time job taking classes towards a degree).

    God Bless,
