This isn't your mother's grilled cheese sandwich though. The secret menu In-N-Out Grilled Cheese is two slices of melted American cheese, hand-leafed lettuce, tomato, spread, with or without onions on a freshly baked bun. This is the vegetarian option at In-N-Out. Sounds like a great snack, right? If you are going for a full meal, we suggest you compliment your Grilled Cheese with another item off of the In-N-Out secret menu, such as Animal Style Fries .
