Preheat your oven to broil on high. Arrange two slices of sourdough bread on a baking sheet and broil for 1-2 minutes until golden brown.

Flip the toasted bread, place sharp cheddar cheese atop one slice, and return to the oven broiling for another 1-2 minutes until melted.

Sprinkle pickled jalapeños evenly over the melted cheese.

On the un-topped slice of bread, spread grainy Dijon mustard and drizzle with honey.

Layer thin slices of Honeycrisp apple, red onion, fresh arugula, and kettle potato chips on the mustard-covered slice.

Carefully place the cheesy side on top, slice the sandwich in half, and serve immediately.
