Pureed summer squash makes a delicious base for this summery squash and corn soup. Start your meal with the soup or enjoy it as a light lunch. Fresh thyme and briny feta cheese give it fabulous flavor. For a variation, try the soup with any herb you have on hand or goat cheese in place of feta.
Heat oil in a large saucepan over medium heat. Add shallot and cook, stirring, 1 minute. Add squash and 1 teaspoon herbs and cook, stirring occasionally, until the squash starts to soften, 3 to 5 minutes.
Add broth and salt; bring to a boil. Reduce heat to a simmer and cook until the squash is soft and mostly translucent, about 5 minutes more. Transfer to a blender and puree until smooth. (Use caution when pureeing hot liquids.) Return the soup to the pan and stir in corn. Bring to a simmer over medium heat and cook, stirring occasionally, until the corn is tender, 3 to 5 minutes more. Remove from the heat; stir in lemon juice. Serve garnished with the remaining 2 teaspoons herbs and feta.
