Gourmet Grilled Cheese Sandwiches

1. Preheat the grill. If you have a grill with a variable temperature control, set it to medium-high (1 or 2 steps below high) or to about 350 to 400 degrees.

2. In a small saucepan melt the butter over low heat. When the butter is melted, whisk in the mustard and garlic. Set aside.

3. Grate the three different types of cheeses into a small bowl and combine with a fork.

4. Put 4 slices of sourdough bread on a large plate. Put 1 tablespoon of scallions on each slice. Place a layer of cheese over the scallions, dividing equally among the 4 slices. Place a slice of sourdough over the cheese and brush the garlic-mustard-butter baste on top.

5. Carefully put each sandwich, basted side down, on the grill. Brush the tops of each sandwich evenly with the remaining garlic-mustard-butter baste.

6. For a 2-sided contact grill: Grill a total of 3 to 4 minutes. For a hibachi grill, combination grill or infusion grill: Grill a total of 6 to 8 minutes (3 to 4 minutes on each side), remove from grill and serve.
