# Expert Suggestions:

01 -
  • It's ready in 40 minutes flat, yet tastes like you've been tending it all day.
  • The beans give you real substance without any heaviness, and that vinaigrette twist keeps everything refreshingly zippy.
  • Naturally vegetarian, gluten-free, and dairy-free, so it works for almost everyone at your table.
02 -
  • Vinegar is assertive—if you add the whole amount at once without tasting first, it can overwhelm; start with the half and build from there if you love tang.
  • The soup tastes even better the next day once all the flavors have nestled together, so don't hesitate to make it ahead.
03 -
  • Use good olive oil—it won't just cook your vegetables, it'll carry flavor throughout the entire pot.
  • Taste the soup before it's done simmering; seasoning is a conversation, not a one-time announcement, and this soup needs you to check in with it.
