2. Choose your fillings. I like roasted asparagus, sautéed mushrooms, rotisserie chicken, thinly sliced ham, basil pesto (especially combined with the following cheese sauce), etc.
3. Make the cheese sauce:
4 Tbsp butter
1/4 cup flour
1 1/2 cups chicken stock
1/4 tsp salt
1/8 tsp pepper
3/4 cup milk
3/4 cup cream
1 cup guyere cheese
3/4 cup shredded parmesan cheese
In a medium saucepan, melt butter over medium heat. Add the flour and cook, stirring constantly until thickened into a pale blonde roux. About 2 to 3 minutes. Add the hot chicken stock slowly, whisking to incorporate. Bring to a simmer and cook, stirring frequently. Add salt and pepper. Slowly whisk in the milk and cream and simmer, stirring until well incorporated and thick. Turn heat to low and add cheeses. Stir until cheese is melted.
