Modelling a stuffed eggplant

Hi, for a university project i have to make a stuffed eggplant, a don’t know how to make
minced meat, tomato sauce and melted cheese, can you help me?

Food is a difficult task, specially for a beginner.
Here is an example what you need to learn for this.

Start with an easy example like this to get a feeling for.

Beside modelling and/or sculpting you need to learn, texturing and materials too. Knowing physics can make melting cheese and sauce easier, too.
