Quick Tomato Soup With Grilled Cheese

Preparation

1. Step 1

   Make the soup: Dump the canned tomatoes and their juices into a medium pot and, using your hands, tear into coarse chunks. Swish the broth in the empty tomato can and add to the pot.

2. Step 2

   Stir in the onion, butter, oregano and sugar, and season generously with salt and pepper. Turn the heat to high and bring to a simmer. Reduce the heat to medium-low, cover and continue simmering, stirring occasionally, until the onion is tender and the tomatoes have broken down, 15 to 20 minutes.

3. Step 3

   Meanwhile, make the sandwiches: Spread a thin layer of mayonnaise on one side of each of the 4 bread slices and evenly sprinkle the cheese and a little oregano on top of the mayonnaise. Top with the cheeseless slices, mayonnaise-side down.

4. Step 4

   Melt 1 tablespoon butter in a large skillet over medium. Add the sandwiches and cook until golden brown on the bottoms, 2 to 3 minutes. Melt the remaining tablespoon of butter in the pan, then flip the sandwiches with a spatula, move them around to coat with the butter and cook until the other side is golden brown and the cheese is melted, 1 to 2 minutes. Turn heat to lowest setting to keep sandwiches warm.

5. Step 5

   Carefully purée the tomato soup using a blender until smooth and creamy, adding more broth if needed to loosen to your desired consistency. Season with salt and pepper. Transfer the grilled cheeses to a cutting board and cut each in half diagonally. Serve alongside the soup.
