A thick-sliced fried bologna sandwich on white bread with mustard is a nostalgic, protein-packed Southern and Appalachian family lunch. Simple, budget-friendly, and full of childhood memories.
Heat a large skillet over medium heat. Melt 1 tbsp butter and swirl to coat the pan evenly.
Score each slice of bologna with a few small cuts along the edge to prevent curling during frying.
Add bologna slices in a single layer and fry for 2-3 minutes per side, or until browned and slightly crispy at the edges. If necessary, fry in batches.
While bologna cooks, spread the remaining butter on one side of each bread slice.
Toast buttered bread slices in a clean skillet or on a griddle over medium heat until golden on each side, about 2 minutes per side.
To assemble, lay toasted bread on a work surface. Spread 1 tbsp mustard on two slices. Top each with 2 fried bologna slices. Close sandwiches with the remaining bread slices and serve warm.
