For a vegetarian version, you can omit the bacon and use a tablespoon of olive oil to cook the onions. Smoky paprika can be added to mimic the smoky flavor of bacon. If you prefer a creamier texture, mix in a couple of tablespoons of sour cream before serving. Another delightful variation is to add a handful of chopped dill pickles for an extra tangy crunch. And if you’re a fan of spicy food, a pinch of red pepper flakes can add just the right amount of heat.
