Instructions:
- Start by cooking the vegetables. Place the beets, potatoes, and carrots in a pot of water and boil until tender. This usually takes about 25-30 minutes, depending on the size of the vegetables. Once cooked, drain the vegetables and let them cool.
- Peel the cooked beets, potatoes, and carrots, then cut them into small cubes. To prevent the beets from coloring the other vegetables, toss them with a bit of vegetable oil immediately after cutting.
- Finely chop the onion and pickled cucumbers.
- In a large salad bowl, combine the diced beets, potatoes, carrots, chopped onion, pickled cucumbers, and green peas.
- To make the dressing, whisk together the vegetable oil, vinegar, mustard, salt, sugar, and ground black pepper (if using) in a small bowl until well combined.
- Pour the dressing over the salad ingredients in the bowl.
- Toss the salad gently until all the ingredients are evenly coated with the dressing.
- Taste and adjust the seasoning if needed, adding more salt, sugar, or vinegar according to your preference.
- Serve the vinaigrette salad immediately, or refrigerate for at least 30 minutes to allow the flavors to meld before serving.
