What it is: A cold salad made with potatoes, eggs, diced meat, and veggies, all coated in mayo.
What's the deal: Salat Olivier shows up on pretty much every Russian menu around the world and is commonly served at celebrations year-round (because nothing says "Happy Sweet 16" like cold potatoes and mayo!). Despite its embrace at the Russian table, it's actually the invention of a 19th century Belgian dude who worked at a Moscow restaurant, which marked the beginning of a Belgian/Russian admiration that still probably exists in Putin's huge collection of Universal Soldier VHS tapes.
