Ham, Cheddar, and Peach Panini

We're right in the middle of peach season, and my Sam's has got some great ones right now.  I like to buy produce locally when I can, but these Sam's peaches are so good that it's hard to pass them up.  We've been eating them with every meal!  Anyway, we had this delicious ham, cheddar, and peach sandwich with a simple green salad dressed with only lemon juice and salt and pepper for dinner.

1 tablespoon Dijon mustard
8 slices whole wheat bread
1 peach, halved, pitted and thinly sliced
4 ounces sliced ham
6 ounces thinly sliced sharp Cheddar

1. Preheat griddle or panini press.
2. Spread mustard on bottom half of each slice of bread, and add half a slice of cheese.  Arrange peach slices on top. Lay ham slices on top of peaches. Sprinkle a little salt and pepper on the peaches, and top with a half slice of cheese, then remaining bread slices.
3. Put sandwiches on buttered griddle or press in panini press, and cook until brown and crisp, 4 to 7 minutes.
