This tomato-based soup is every bit as satisfying but much lighter than cream-based chowders. Potatoes, white beans and corn provide substance and flavor. Serve this speedy weeknight soup with crackers on the side.
Heat a Dutch oven over medium heat. Add cooking oil and carrots, garlic and white parts of green onions with a pinch of salt. Saute until onions are tender, ~3 minutes. Add thyme and cook for 1 minute more.
Add potatoes, tomatoes (including juice) and stock. Cover and bring to a boil and then simmer covered until potatoes are nearly tender, ~10 minutes (more or less depending on size of potato pieces).
Stir in beans and corn and continue simmering uncovered until warmed through, ~3 minutes more.
Serve chowder topped with green parts of green onions and with crackers on the side. Enjoy!
