What to eat its day 3 of tonsillectomy?

Anything you want: I tend to not restrict diet in any way. Some ents say to stick to a soft diet but that is more of an older way of thinking. If there was something more difficult with your surgery your doctor may give you specific instructions on what not to eat- obviously follow that. Be sure to stay hydrated. Beyond that, hot, cold, dairy, bubbly, juice, bread, chicken, pizza, you name it... Chow down.
