Favorite Sausage-Potato Salad

Bring a large pot of water to a boil. Add the potatoes; boil about 25 minutes or until tender. Drain and let cool. Cut potatoes into quarters and place in a large bowl. In a large skillet, heat the 2 teaspoons oil over medium-high heat. Brown the kielbasa. Transfer to a paper towel-lined plate to drain. Add kielbasa to the bowl with the potatoes. For the dressing, in a small bowl, whisk together the vinegar, mustard, garlic, salt, and pepper. Slowly whisk in the 3 tablespoons oil. Add the dressing, celery, and green onions to the potato mixture and toss to combine. Serve warm or at room temperature.
