From another site:
Avoid chocolate, onions, eggplant or tomatoes as they are hard for your pet to digest and could potentially cause health risks.
Don’t add fillers (rice, wheat, corn, soy, grain, etc.) since your pet wouldn’t find these in the wild.
Avoid sharing your dinner with your pet, unless what you are eating is fresh and doesn’t include any dangerous ingredients.
