1 packet Good Seasons Italian dressing mix
1 (7-8 oz.) pkg. elbow macaroni, cooked
1 1/2 c. grated Swiss cheese
2 (6 oz.) cans tuna in water
1 c. chopped ripe olives
1 box frozen green peas and onions
1 (6-7 oz.) bottle creamy Italian dressing

Toss macaroni and cheese together with 1 packet Good Seasons Italian dressing mix while macaroni is still warm. Let mixture sit in refrigerator for a couple of hours. Then add the rest of the ingredients, tossing well with bottled dressing. Refrigerate. Just before serving, add a little more dressing (Italian, Ranch, mayonnaise or whatever) if the salad needs more moisture.
