This is a modification of another recipe that calls for the standard butter, white wine and sherry. I substituted cooking spray for the butter, and used a guiness stout in place of the wine and sherry.


  1. Slice onions thinly, and saute in a skillet liberally sprayed with cooking spray (i.e., Pam, etc.), until limp and lightly carmelized.
  2. Place in crock pot, add stout, broth, and worcestershire sauce, crush garlic and add, stir well.
  3. Cook 4-6 hours on high heat, or 6-8 on low.
  4. Top with slice of dense artisan bread or crostini and a slice of lowfat Provolone, place briefly under a broiler to melt and brown cheese, and serve.
