hey Sandra, do I rly need to use slow cooker for this soup? got none at home, maybe i can just use a pot on the stove?
hey larry, i tried with a pot once, takes a bit of stirring but works fine!
Love how versatile this recipe is! I swapped meat broth for veggie, turned out great.
if I add chocolate instead of veggies, does it still count as soup asking for a friend
Honestly, doesn’t seem anything special. Just another soup recipe. Why bother when you can buy ready-made?
Tried this last night and it was a hit with the family! Love the step-by-step guide, Sandra. Makes it foolproof!
Not sure if slow cooker makes any difference. Isn’t this just like any other soup?
it’s about the flavors merging slowly, Steve! Makes a big diference.
soup without meat, why even bother
this looks easy enough for weeknights, gonna try! thanks Sandra!
Interesting use of a slow cooker. I wonder if a programmable pressure cooker could expedite the process without sacrificing flavor.
