Still Life

As above, you can create a still life from pretty much any inanimate objects. A bowl of fruit is the classic as it provides a variety of shapes and colours, but I've seen it done with a plate of potatoes and a ladies red stiletto shoe! How about cooking a full dinner and laying the table out with your best dinner service and linens. Provided you can light it well, you simply need to take pictures from various angles etc at different intervals of the meal. If you shoot before you lay out the food, then after serving, during eating and after eating (dirty plates, spills on the tablecloth etc) you should be able to pick out a great assignment shot or selection depending on your brief.
