You only really have a case for being served a "raw burger" if you got sick or sustained severe mental distress.
If you were only served the raw burger, but, did not eat it and noticed it right away and complained, you do not have a claim that is worth any money.
If you did eat it and get sick you probably do have a claim. As to how you file a suit yourself, if your case is worth less than $3,500 you could file it is Small Claims Court.
The Nebraska Supreme Court's website has information on how to file a Small Claims Court case. However, the fast food restaurant has the right to move the case to County Court, where it could employ an attorney to defend it.
If the case is worth more than $3,500, a lawsuit starts by you filing a Complaint. The contents of the Complaint and what else needs to be done is too difficult to explain in this response.
I would suggest contacting a personal injury attorney to discuss your case. Most offer a free initial consultation and you can learn more about your rights and options.
