It is quite simple to make food from FIMO.
For the Edam Cheese just roll a pale yellow ball and flatten it out a bit. Roll out a really thin layer of red and wrap it around the yellow. Cut a slice out so that you can see the "cheese" inside, and have a slice to display.
For a cauliflower, roll some white Fimo into a ball and poke small holes into it. Wrap small green layers around it to be the leaves.
To make bread or rolls, just shape some cream coloured Fimo into whichever bread shape that you want. When you have baked it and it has hardened put a little brown paint/tea onto the outside.
