Easy Tomato Soup

• ¼ cup (½ stick or 55 g) unsalted butter
• ½ l

Directions

• 1 In a large saucepan over medium heat, melt the butter.
• 2 Add the onion, stock, tomatoes (with all the juices), and salt. Bring to a simmer and cook, uncovered, for about 40 minutes, stirring occasionally so the soup doesn’t stick to the bottom of the pan.
• 3 Turn off the heat and let the soup cool for about 10 minutes.
