### Instruction: What are the defining characteristics of a Ramly Burger?
### Input: Aside from producing burger meat and other frozen foods, the company is also known for its street stalls, which have sold the Ramly Burger in every state in Malaysia since 1979. The defining characteristic of a Ramly Burger is the patty itself wrapped in an omelette and topped with several condiments, which may include ketchup, mayonnaise, chili sauce, Worcestershire sauce, and/or Maggi seasoning, depending on the vendor. The term "Ramly Burger" has been used as a genericized trademark for similarly-prepared burgers which are not necessarily made with the Ramly beef patty as well. They are considered a local favourite, especially by city dwellers. It is estimated that there are over 25,000 Ramly Burger stalls nationwide as of 2015, with the monthly average income of about RM 5,000.

The burger (patties) has been banned in Singapore due to the meat coming from sources which are not on the Agri-Food and Veterinary Authority of Singapore approved list of Commercial Food Imports for Meats which could pose a potential health risk. Singaporean street vendors continue to use the Ramly Burger wrapper.
