It's not a gluten issue for my family. There is something in wheat generally that causes huge histamine reactions. But I think I can make some cheese quesadillas with tomato soup and it would work perfectly. It's obviously not tomato soup and grilled cheese, but it comes close.
We used to have soup after the Stations of the Cross during Lent at our church. Cheese tortellini in vegetable broth with carrots and other vegetables. It’s actually easy to make. Buy the tortellini ready made. Crusty bread. Salad. Edit: It was after Mass and before the Stations.
