Simple and Delicious Kale Soup

Step 1

Melt butter in a pot over medium-high heat. Saute onion in hot butter until tender, 5 to 10 minutes. Stir chicken broth and tomato into onion.

Step 2

Heat broth mixture to near-boiling and stir kale into liquid until completely submerged. Cook until kale wilts, 3 to 5 minutes. Stir beans into soup and cook until heated through, another 2 to 3 minutes.
