Aunt Margie's Vinegrette Cole Slaw

We have this cole slaw every Mother's Day when we have our grilled hamburgers and hot dogs! It's delicious!

----
Mix in a bowl:

1 tsp. salt
1/4 tsp. pepper
1/2 tsp. dry mustard
1/2 tsp. celery seed
2 Tbsp. sugar
1/4 cup chopped green pepper (optional)
1 tsp. instant minced onion
3 Tbsp. salad oil
1/3 cup white vinegar

Pour over 4 cups cole slaw (one bag of store bought cole slaw will do it!) and stir well. Chill for at least 3 hours before serving.

**Note**
I've only made this once, but found that it was much better chilled. When I tried it right after I made it, it was way too vinegary.
