Make this fried bologna sandwich now

A fried bologna sandwich is not highfalutin food, but every now and again, it’ll cure what ails you. In a nonstick skillet over medium-high heat, brown an onion sandwich bun, cut sides down, 2 minutes. Remove the bun and set aside. Cut four ¼-inch slits at the edges of a ¼-inch-thick slice of bologna to prevent it from curling while frying. Over medium-high heat, warm 1 tablespoon canola oil in the skillet. Cook the bologna until the bottom is nicely browned, then flip and cook 1 minute more. Remove and set aside. Crack an egg into the skillet and season to taste with freshly ground black pepper. Fry the egg 1 minute, flip and cook to desired doneness (we like a runny yolk). In a small bowl, whisk together 1 tablespoon mayonnaise, 1 teaspoon sweet pickle relish, 1 teaspoon stone-ground mustard and ¼ teaspoon freshly grated horseradish. Spread the mayo mixture on the toasted bun. Place the cooked bologna on top, followed by the fried egg. Top with the bun and serve immediately.
