My idea of making my own salad dressing is a packet of dry ranch and some mayonnaise. I love Catalina salad dressing and so decided to make one myself.
1 cup salad oil
1/2 cup Splenda or a little less or 3/4 to 1 cup of white sugar
1 can of tomato soup
1/2 cup white vinegar
1 tablespoon worcestershire sauce
1 teaspoon mustard powder
1 teaspoon onion powder
1/2 teaspoon pepper
Put everything into a blender and mix. As I said, this was really easy and I think it's delicious.
