Potato Salad (Olivier Salad) (Russian Vegetarian)

Cut the potatoes and carrots into small, uniform cubes.
Place them in a large pot and fill with water.
Add salt and vinegar. Bring to a boil over medium-high heat, then reduce heat to medium and continue cooking until potatoes are cooked through, about 15 minutes. Drain the potatoes and let cool to room temperature.
Meanwhile, cut the sausage and pickles into small cubes and chop the chives.
Also cut the hard-boiled eggs into small cubes.
If using fresh dill, chop that too.
In a large bowl, combine the potatoes, carrots, sausage, pickles, peas, and green onions.
Add mayonnaise and dill and mix until well combined.
Salt and pepper to taste. Cover with plastic wrap and refrigerate for at least 1 hour before serving.
