About 4 big servings.

• 1/2 head of a medium cabbage
• 2 medium to big carrots
• 1 small to medium onion

Shred or grate the carrots.
Chop or shred the cabbage (whatever shape you are used to).
Chop or grate the onion.
Toss all together in a large bowl.
In another bowl or in a container with a lid, mix

• 1 C mayonnaise, non-fat, low-fat, or full fat (see notes below)
• 1 T sugar
• 1 T vinegar (flavored is nice, we like sage, but use what you have)
• 1 teaspoon celery seed
• a grind of black pepper
• Water or soy milk to thin to desired consistency

If using a jar, put lid on and shake until blended.
Otherwise, mix with fork for whip until smooth.
Taste to see if you think it needs more vinegar or sugar.
If its too thick, add a little water or milk to thin, a spoonful at a time.
Pour dressing over the vegetables, starting with 1/2 C, and toss.
Add more dressing if this seems too dry.
My husband thinks this is too dry, so I make extra dressing for him to add to his portion (he likes it really creamy).

If you don't have celery seed, leave it out.
If you don't have any onions, use onion powder in the dressing instead of grated onion in the vegetable portion.

This keeps very nicely overnight in the refrigerator and is also good fresh made.

Some notes on mayonaise:

I don't make mayonnaise.
Have used silken tofu or regular tofu run through the blender and thinned with water to make a sauce in a pinch (for pasta, even), but it just doesn't taste the same.
But then a lot of people don't mind the difference.
Haven't blind tasted tested it though on friends.
Have been TOLD, although never tried it, that cooked white beans (like navy beans), blended, with a little lemon and mustard and thinned with water is also OK.
Any "creamy" flavor carrier that you like can be used, as long as it takes "sweet/sour" well.
A lot of our mayo in the US no longer contains eggs (low fat and fat free are getting to be like religious movements here) and some no diary.
Soy mayo is easy to find and we have several companies that issue catalogues and will ship to your house by mail or other carrier.
