Remove the core from the cabbage, and julienne. In a pot, sauté the cabbage in olive oil over a low heat for 20 minutes, stirring constantly. Lightly season with salt. Add the red wine and cook off the alcohol, about 3 to 4 minutes. Next add the vinegar and simmer on a low heat until the cabbage is very tender. Transfer the mix to a blender, purée until smooth, and adjust the seasoning with salt and pepper.
