Pasta Salad

1 package of tiny shells, cooked
2T. McCormick Salad Supreme Seasoning
1/2 c. Italian salad dressing
1/4 c. red wine vinegar (if you have it)
Cook pasta, cool by running water over. Drain. Mix other ingredients and toss with pasta. Mix often as sauce will settle to bottom of bowl.

Edited to add: I didn't use the red wine vinegar and I thought it needed something so I grated some Muenster cheese and added it. Maybe about a half a cup.
