Step 1

Warm a tablespoon or two of oil in a large soup pot. Add onion and cook until soft, then add garlic and cook for one minute. Do not let the garlic brown.

Step 2

Add potatoes and broth/water, along with the bay leaves. Bring the mixture to a boil. Reduce heat to a simmer. Cover the pot and cook until potatoes are very tender, about 20 or so minutes.

Step 3

Remove bay leaves and discard. Ladle 2 or 3 cups of potato cubes from the pot, into a heat-proof bowl. Blend the soup remaining in the pot with an immersion blender until the broth is smooth and creamy with rough chunks of potato here and there. You can use a food processor instead of the immersion blender, but do not over process. Add potato cubes back into the pot.

Step 4

Bring soup back to a gentle simmer and add the greens and tomatoes, plus 1/2 teaspoon salt or more (depending on whether you are using water, or the saltiness of your broth). Taste the soup to decide how much salt to add. Cook until greens are wilted and tomatoes are barely soft, about 2 - 4 minutes.
