Hidden inside these tame-looking burgers is a smoky and spicy blend of bacon, chipotle, cheese and something unexpected — pepperoni. Because the ground-beef part of these burgers is patted fairly thin, there’s less of a chance you’ll undercook it. For a little extra texture and flavor, crispy fried onions go into the beef.
They can be cooked in a grill pan on the stove top as well; grease the pan with cooking-oil spray and cook over medium heat.
A kitchen scale comes in quite handy for weighing the portions of meat.
These burgers taste great unadorned, but feel free to top them with accompaniments of your choice.
