Grilled Cheese With Sliced Apple and a Little Whole Grain Mustard on Sourdough Bread

• 4 slices sourdough bread
• 4 sandwich-sized slices of KRAFT cheddar cheese
• 2 T. whole grain mustard, divided
• 1 apple, cored and cut into thin slices
• 2 T. butter

1. Heat a large skillet over medium heat.
2. While skillet heats, spread mustard thinly over all slices of bread.
3. Lay one slice of cheese and layer apple slices on one piece of bread per sandwich. Gently join the two halves, so that each has a layer of apple in the middle.
4. Put half the butter into heated skillet and coat skillet surface with the melting butter. When butter is melted, place sandwiches in skillet.
5. Cook sandwiches on medium heat, so cheese has time to melt, but the bread doesn't burn. Use a spatula to check on the grilling bread's progress.
6. When first side is toasted and cheese has begun to melt, gently flip the sandwiches. Slip remaining butter into skillet just before flipping the sandwiches, to brown the other side of sandwich.
7. When the cheese has melted and the bread is golden brown, remove from the skillet and serve.
