Bring a large pot full of water set over high heat to a boil. Cook macaroni according to the package's instructions, drain and rinse with cold water. Toss the noodles with a tablespoon of olive oil.While the pasta is cooking, in a large mixing bowl whisk together the mayo, half & half, mustard, pickle juice, relish, dill, salt and pepper. Pour the cold pasta (that has been tossed in the olive oil) into the bowl and add the cubed cheese. Stir with a spatula to combine. The mixture may be a bit runny, but as it chills it will soak up the moisture. Cover and place in the refrigerator for at least 1 hour.
