Recipe for coleslaw sauce 

Put in blender: 
1 cup of cooking oil (I prefer light olive oil) 
1 teaspoon salt, 
1 cup sugar, 
1 teaspoon dried mustard, 
1 teaspoon celery seed, 
1/2 cider vinegar, 
1 small sweet onion diced. 

Blend until mixed. Store in refrigerator until used. 
I keep mine in a glass jar, it keeps for a week or two. 
I like to put shredded carrots, red cabbage & green cabbage in my slaw. 
For those who like more green add sm pieces of green pepper. 
Let refrigerate several hours before serving.
