To make it vegetarian, just sauté the onions in a tablespoon of olive oil and leave out the bacon. If you want your bacon to taste like smoke, try adding some smoked paprika. Before serving, stir in a few tablespoons of sour cream if you want a creamier consistency. Adding some chopped dill pickles for an additional bitter bite is another delicious variant. And if you like things on the spicy side, a sprinkle of red pepper flakes will do the trick.
