Triple Mustard and Gruyere Bread Thins

Directions

1. In a small bowl, dissolve yeast in warm water. In a large bowl, combine egg, oil, minced onion, stone-ground mustard, ground mustard, onion powder, salt, yeast mixture and 2 cups flour; beat on medium speed until smooth. Stir in enough remaining flour to form a soft dough (dough will be sticky). Stir in cheese.
2. Turn dough onto a floured surface; knead until smooth and elastic, 6-8 minutes. Place in a greased bowl, turning once to grease the top. Cover and let rise in a warm place until almost doubled, about 1-1/2 hours.
3. Punch down dough. Turn onto a lightly floured surface; divide and shape into 18 balls, about 2 ounces each. Flatten each ball to a 4-in. circle. Place 2 in. apart on greased baking sheets. Cover with kitchen towels; let rise in a warm place until slightly puffed, about 30 minutes.
4. Preheat oven to 375°. Brush rolls with Dijon mustard; if desired, sprinkle with seeds. Bake until lightly browned, 15-18 minutes. Remove from pans to wire racks to cool completely.
