???? From Me to You
This soup is one of my personal favorites for meal prepping — it stores and reheats beautifully. I love pairing it with a grilled cheese sandwich or toasted sourdough. It’s also a lovely vegan option for holiday dinners or clean-eating resets in the new year.
To elevate it further, drizzle a little truffle oil on top — pure luxury in a bowl.
