Kim's Summer Cucumber Pasta Salad

Step 1
Bring a large pot of lightly salted water to a boil. Cook pasta at a boil, stirring occasionally, until cooked through yet firm to the bite, about 12 minutes. Drain and rinse several times with cold water until pasta is cool.

Step 2
Stir pasta, cucumber, onion, and dill in a salad bowl.

Step 3
Whisk vinegar, sugar, water, vegetable oil, mustard, salt, and black pepper in a separate bowl until sugar and salt have dissolved. Pour dressing over pasta mixture and toss lightly to coat with dressing. Let chill for 2 hours before serving.
