Fill large pot with water and 1/2 tablespoon olive oil then place on stove top over medium-high heat.
Cook pasta according to directions ( I cooked mine for 9-11 minutes ) then rinse under cold water and allow water to drain.
Meanwhile, add the diced cucumber, green onions, cheddar cheese, and grated parmesan cheese to a large bowl.
Slice dill pickles and add to the bowl.
Stir in 1 cup mayonnaise, 3/4 cup sour cream, 4 tbsp pickle juice, 1/2 tbsp mustard, 1/2 cup milk/cream, 1/2 tsp pepper, and 1/4 tsp red pepper flakes.
Once pasta has drained, add it to the bowl.
Toss dill pickle pasta salad together until combined well.
