Fill a large bowl with cold water. Peel the potatoes and put them in the cold water to keep them from browning.
In a large food processor fitted with the s-blade, finely chop the onions. Put the chopped onions into a large bowl. Quarter the potatoes and finely chop them in a food processor. Add the potatoes to the onions. Add half of the chives, the eggs, flour, salt, and pepper to the potatoes and onions. Mix well until combined.
In a large skillet on a high flame, heat canola oil for frying (about 2 cups). You can see if the oil is ready by dropping in a spoonful of batter; if the oil sizzles it's ready to fry. Adjust the flame to medium-high. Add 1⁄4 cup of batter to the oil at a time (don't overcrowd pan). Give each latke about three minutes on each side, or until browned. Drain latkes on layers of paper towel to take away excess oil.
Dipping Sauce:
In a small bowl, whisk together the Greek yogurt and horseradish sauce. Mix in the remaining chives, parsley, salt, and pepper.
