A thick, solid cutting base with 6 color coded interchangeable cutting mats to eliminate cross contamination. Cut your chicken up, remove the cutting mat and insert another one for your vegetables.
The mats also make it easy to carry chopped ingredients to the stove - just curl the mat up and pour into the pot.
PROS: Eliminates cross contamination and saves storage space. Flexible cutting mats allow easy transfer from board to pot.
CONS: The cutting board base and mats tend to slip around.
