If you have a blender at home you can make vegetable soup. Trader Joes has relatively decent packaged soups. Greek yogurt and smothies are also good options. You can buy protein powder and add to smothies or apple sauce. Another trick that I used when I had oral surgery and did not have time for cooking - baby food. You have to add salt, but it Is OK and you can last on it for a few days. It is super easy to eat after the surgery and portable.
