The Moroccan is now accused of murdering her boyfriend then chopping up his body and serving it to Pakistani workers in the United Arab Emirates.
Prosecutors now allege that she butchered him, cooked his body and put it in a traditional rice and meat dish known as machboos.
Prosecutors in Al-Ain emirate said the woman, who is said to be in her 30s, was arrested on suspicion of killing her boyfriend of seven years after he told her of his plans to marry another person from Morocco, the National newspaper in Abu Dhabi reported.
However, after further questioning, she allegedly admitted that she killed him in a moment of "insanity" and that she wanted revenge for being dumped.More news: Victims recount horror of deadly Kabul blast as toll rises

It was gathered that after the deceased's brother showed up at the suspect's home, she claimed to have kicked him out and did not know where he was.
The woman reportedly confessed to using a blender to mince her lover's flesh after she killed him. The victim's brother, however, found the tooth in the blender and then reported the woman to the authorities.
Police carried out DNA tests on the tooth and confirmed it belonged to the victim after his brother went to them to report the incident.
A court date will be set once police have completed their investigation. During interrogation, the woman said she took help from a friend, who helped her clean the apartment after the crime.
