→ Beans

01 - 1 cup canned kidney beans, drained and rinsed
02 - 1 cup canned cannellini beans, drained and rinsed
03 - 1 cup canned green beans, cut into 1-inch pieces, drained

07 - 2 cloves garlic, minced
08 - 1 cup cherry tomatoes, halved

→ Broth & Seasonings

09 - 4 cups low-sodium vegetable broth
10 - 2 tablespoons olive oil
11 - 2 tablespoons red wine vinegar
12 - 1 tablespoon Dijon mustard
13 - 1 teaspoon sugar
14 - 1/2 teaspoon dried oregano
15 - 1/4 teaspoon crushed red pepper flakes
16 - Salt and black pepper to taste
17 - 2 tablespoons fresh parsley, chopped

# How to Make It:

01 - Heat 2 tablespoons olive oil in a large soup pot over medium heat. Add chopped red onion, diced celery, and minced garlic. Sauté for 3 to 4 minutes until vegetables are softened and fragrant.
02 - Stir in diced red bell pepper and cook for 2 additional minutes until slightly tender.
03 - Add kidney beans, cannellini beans, green beans, and halved cherry tomatoes to the pot. Sauté for 1 to 2 minutes, stirring occasionally.
04 - Pour 4 cups vegetable broth into the pot. Bring to a gentle boil over medium-high heat, then reduce heat to low and maintain a simmer.
05 - In a small bowl, whisk together red wine vinegar, Dijon mustard, sugar, dried oregano, and crushed red pepper flakes until well combined.
06 - Add the vinaigrette mixture to the pot. Simmer soup uncovered for 15 minutes, allowing flavors to fully develop and meld together.
07 - Taste the soup and adjust seasoning with salt and black pepper as needed. Stir in chopped fresh parsley.
08 - Ladle soup into individual bowls and garnish with additional fresh parsley if desired. Serve hot or at warm temperature.

# Expert Tips:

01 -
  • It comes together faster than you can set the table, which means weeknight dinners don't have to mean takeout.
  • The vinegar-and-mustard punch makes it taste intentional and special, not like you're just boiling canned beans.
  • It's naturally plant-based and gluten-free, so you're not limiting anyone at the table without realizing it.
02 -
  • Don't skip rinsing canned beans, even if you're in a hurry—the starchy liquid they sit in can make your soup cloudy and overly thick.
  • The vinegar balance is everything here, so taste before adding all of it and adjust to your preference rather than just dumping it in.
03 -
  • If your canned beans are already soft, reduce the simmering time by 5 minutes so they don't fall apart and turn mushy.
  • The difference between good and great here is often that extra minute you spend making sure your onions are fully soft before adding the bell pepper—patience in the beginning pays off in the bowl.
