When I do burgers, I'm a big fan of adding home made pickled red cabbage to them, it gives them a really good clean, sour bite, very similar to carrot and daikon in banh mi. To make it, I just bring to boil a mix of water, vinegar, salt, sugar, and spices (usually cloves and caraway), then pour it into a mason jar with the shredded cabbage, and put it in the fridge for a couple of days. I've tried using sauerkraut, but it's a bit too pickled and mushy for burgers, and usually drips everywhere.
