makes one sandwich
2 thin slices sourdough bread
1 teaspoon unsalted butter
2 teaspoons (or more!) whole-grain Dijon mustard
1/2 green apple, cored and thinly sliced (I ended up using the whole cored apple, and added the extra grilled apple slices to my salad)
white cheddar cheese, thinly sliced (cut enough slices to cover both slices of bread)
1. Heat a grill pan over medium-high heat.
2. Brush the grill pan with olive oil or spray lightly with cooking spray.
3. Grill the apple slices for about 3-5 minutes per side. Remove from the heat.
4. Butter one side of each slice of bread. Flip each slice of bread over and add about a teaspoon of mustard (or more if you're a mustard fan like me!) to each slice.
5. Add to the mustard-covered sides of each bread slice a layer of thinly-sliced cheddar cheese followed by a layer of grilled apple slices.
6. Carefully sandwich the two slices of bread together.
7. Place the sandwich on the grill pan and grill for 2-3 minutes per side, or until the bread is golden brown and the cheese has begun to melt. (I like to use my grill press to really smoosh the sandwich to help get the cheese nice and melty.)
8. Serve immediately.
