In a large pot, bring potatoes to a boil in salted water over high. Reduce to a simmer and cook until tender when pierced with a knife, 15 to 20 minutes. Drain and cut potatoes (when not too hot to touch) into 1½" pieces. Place in a bowl and drizzle with vinegar. Set aside.
Meanwhile, bring water to boil in a medium pot. Gently place eggs in the water and boil for 12 minutes. Drain and place in a bowl of ice water. Let cool and cut into quarters.
In a medium bowl, whisk ricotta, tzatziki, honey mustard, salt, and peppers. Fold in cilantro and green onions.
Pour sauce mixture over potatoes and stir with a wooden spoon until all potatoes are coated. Stir in chopped bacon.
Pour salad into serving bowl. Sprinkle with remaining greens and arrange eggs. Refrigerate until ready to serve.
