1 1/2-2 lbs. new potatoes
2 onions, finely chopped
1/2 c. oil
3 tbsp. lemon juice
Salt
Freshly ground pepper
1/2 tsp. sugar
1 tbsp. parsley or chives

Boil the potatoes, making sure they are not too soft. Cool them and peel. Cut them into slices and place them in a mixing bowl with the chopped onions. Prepare dressing by vigorously mixing the remainder of ingredients together. While the potatoes are still warm, pour the dressing over them and mix them gently. Serve at room temperature.
