After having mine done I was advised not to eat anything for the first hours after having it done, but during the healing period anything really soft, starting with say eggs and what not, but to be honest it depends on the person, one of the people I knew was able to eat more solid food much faster than I was, but really just anything that wont let the healing skin tear again so like person before me liquidised soups are ure best bet, and pasta I found I could eat if I ate with side of my mouth.
Soup. Jello. Pudding. Call the place that pierced it and ask them.
