Ham and Cheese Kolaches

• 3 to 3-1/2 cups all-purpose flour
• 1/4 cup grated Parmesan cheese
• 1 tablespoon sugar
• 1 envelope yeast
• 1 teaspoon salt
• 1 cup water
• 2 tablespoons butter or margarine
• 1 egg, large
  
  Ham and Cheese Filling
• 1 cup diced ham
• 1/2 cup shredded Swiss cheese
• 1/4 cup grated Parmesan cheese
• 2 tablespoons Dijon mustard.
  
  Egg Glaze
• 1 egg white
• 1 tablespoon water
  
  In a large bowl, combine 1 cup flour, cheese, sugar, undissolved yeast, and salt. Heat water and butter until very warm (120 to 130 degrees F). Gradually add to flour mixture. Beat 2 minutes at medium speed of electric mixer, scraping bowl occasionally. Add egg and 1 cup flour; beat 2 minutes at high speed. Stir in enough remaining flour to make a soft dough. Knead on lightly floured surface until smooth and elastic, about 8 to 10 minutes. Cover; let rest 10 minutes.
  
  Divide dough into 16 equal pieces; shape each into a ball. Cover; let rest 15 minutes. Place balls on greased baking sheets 2 inches apart. Make a deep and wide indentation on each ball by pushing outward toward edge, leaving 1/2-inch ridge around outside. Fill with Ham and Cheese Filling. Cover; let rise in warm, draft-free place until doubled in size, about 1 hour. Brush surface of dough with Egg Glaze.
  
  Bake at 375oF for 15 minutes or until done. Remove from sheets; serve warm. Refrigerate leftovers.
