How to Make It
Process bologna through a spiralizer fitted with the large triangle-shaped hole attachment to create bologna “noodles.”
Melt butter in a large nonstick skillet over medium-high. Add bologna, and cook, turning occasionally, until browned and slightly crispy, 3 to 5 minutes. Transfer to a plate lined with paper towels to drain.
Spread mayonnaise evenly on 3 of the bread slices. Top each with 1 cheese slice. Top evenly with the fried bologna, chips, and lettuce. Spread mustard on remaining 3 bread slices; place on top of sandwiches.
