Beat the eggs well and stir in the sliced onions. Sprinkle the flour over the top and stir it all together to coat the onions. Drop small batches at a time into the frying oil and fry until they're golden brown. Remove with a large slatted spatula and drain on a paper towel until your burgers are ready. Sprinkle with sea salt. Good luck staying out of them before it's time to assemble your burgers! We make extra so we can snack on them as they come out.
