Preheat your oven to 375°F (190°C). Slice fresh apples and toss them with a sprinkle of cinnamon and nutmeg. Arrange the apple slices on a baking sheet lined with parchment paper, then roast for about 15-20 minutes until tender and caramelized.

In a skillet over medium heat, cook the bacon until crispy, about 6-8 minutes. If you're using sweetened bacon, sprinkle a bit of sugar while it cooks to create a caramelized finish.

Spread herb butter generously on the outer sides of each slice of bread.

On the unbuttered side of one slice, layer the roasted apples, slices of sharp cheddar cheese, and crispy bacon. Top it with another slice of bread, ensuring the buttered sides are outside.

Grill the sandwich over medium-low heat for about 4-5 minutes on each side until the bread is golden brown and the cheese has melted.

Remove the sandwich from the skillet and let it cool slightly. Slice it in half and serve warm with a side of mixed greens or light soup.
