I found this one in a Better Homes & Garden book a friend of mine gave me. And since I prefer to make things from scratch and not come out of a box or bottle, this one suited me just fine.
1 cup vegetable oil(Use what you have but it should be a light oil)
1/4 lemon juice
1/4 cup white vinegar
1/2t dried oregano
1/2t dried mustard
1/2t onion powder
1/8t ground thyme
2 cloves crushed garlic
Shake all ingredients in tightly covered jar. Refrigerate at least 2 hours.
Yield: 1&1/2 cups(24 Tablespoons)
