Like No Other Pasta Salad

1 (16 ounce) package penne pasta

½ large onion, chopped

½ large cucumber, sliced

½ cup canola oil

½ cup white vinegar

½ cup white sugar

1 ½ teaspoons garlic powder

1 ½ teaspoons salt

1 ½ teaspoons ground mustard

1 ½ teaspoons dried parsley

½ teaspoon ground black pepper

Bring a large pot of lightly salted water to a boil. Cook penne at a boil until tender yet firm to the bite, about 11 minutes. Drain and rinse under cold water. Transfer to a large bowl.

Blend onion, cucumber, canola oil, vinegar, sugar, garlic powder, salt, mustard, parsley, and pepper in a food processor or blender until smooth, about 2 minutes.

Pour sauce over pasta; toss to coat. Refrigerate 8 hours or overnight.
