I used to be on faculty in an orthodontic department at a dental school. in the olden days, when patients had their jaws restructured, we wired their mouths shut for 6 weeks. i cannot imagine! They learned creative ways to get food in. one gal would put a cheeseburger in a blender and turn it into a shake! i suppose after awhile, even a cheeseburger shake might sound good.

Hopefully, you can find some options that you will enjoy
