this needs to highlight features, emphasize professionalism, be interactive, and be concise and clear.

1. Highlight features: First of all, highlight your catering features, such as what cuisine you are good at and what unique tastes or styles you have. These are all attractive places.

2. Emphasize professionalism: If you have rich experience or professional skills in the catering industry, you can emphasize it in the introduction to let the audience feel your professionalism.

3. Interactivity: You can write something with strong interactivity, such as "Welcome everyone to taste my food, and remember to leave your's suggestion!" This can increase the interaction with the audience and improve the degree of attention.

4. Concise and clear: The introduction should be concise and clear, not too complicated, so that people can grasp the key points at once.
