Raspberry Grilled Cheese Sandwich

2 slices sturdy bread
1 tablespoon butter, room temperature
12 fresh, ripe raspberries 
2 ounces cheddar cheese, sliced or grated

1. Butter both pieces of bread on one side using ½ a tablespoon of butter for each. 
2. Place the raspberries on the unbuttered side of one piece of bread and place the cheese over the berries. Cover with the other bread slice, buttered side up.
3. Heat a heavy skillet over medium heat and put the sandwich in the pan. (Or use a panini grill.) Press down while the sandwich is cooking with a metal spatula. Cook for about four minutes per side or until each side of the bread is golden brown and the cheese is melted.
