# Expert Advice:

01 -
  • It captures that nostalgic three-bean salad flavor but transforms it into something cozy and new
  • The tangy vinaigrette base creates depth you never get from ordinary vegetable soup

02 -
  • Do not skip sautéing the vegetables first because that foundational sweetness makes all the difference
  • The vinegar might smell strong at first but it mellows beautifully into the broth during simmering
  • This soup actually tastes better the next day as the beans continue to absorb the vinaigrette
03 -
  • Rinse your canned beans thoroughly to remove any metallic taste that might compete with the vinaigrette
  • If the soup feels too acidic, add a pinch more sugar rather than salt to balance
