# Expert Advice:

01 -
  • It comes together in under 40 minutes, which means weeknight dinner without the stress or compromise.
  • The vinegar and mustard give it a sophistication that makes people ask for the recipe, even though it's genuinely simple.
  • Three different beans mean every spoonful is different, and it stays interesting all the way through the bowl.
02 -
  • Don't skip draining and rinsing your canned beans—that's where the metallic taste hides, and getting rid of it changes everything.
  • The vinegar mixture needs to be whisked properly so the mustard helps suspend the vinegar throughout the broth; otherwise you get pockets of sourness instead of balanced brightness.
03 -
  • If you want to make this vegan, it already is—just double check your vegetable broth and you're golden.
  • The secret to this soup tasting like more than the sum of its parts is not rushing the initial sauté of your aromatics and then not skipping the vinaigrette step; that's where the magic lives.
