Instructions
Shred cabbage through apple in a food processor (or chop fine by hand). Transfer to a large bowl and mix with oregano and red pepper flakes.
Spoon cabbage mixture into 2 quart-sized jars and press down with the back of a wooden spoon. Leave 1 inch of space between the top of the cabbage and the top of the jar.
In a small bowl, mix the salt with the vinegar and water. Pour evenly over both jars of the cabbage, then add more water to both, if needed, so that the liquid is level with the cabbage.
Cover jars tightly and leave at room temperature for 3 days. Store long-term in the refrigerator.
