My favorite pasta salad dressing was always the packet of PSV from McCormick. I haven't been able to find it in a couple of years and finally went to the McCormick site only to find out that it's not available any longer. But they did post a recipe!!! I haven't tried it yet but wanted to post it for anyone else who might be looking for the same. Note: prep time does not include the refrigeration time that is required. I like to use tri-colored pasta and sometimes I throw in some cubes of cheddar cheese, too.
