Lightly grease or place parchment on half sheet pans. With pizza cutter or sharp knife, divide each demi loaf into 2 (large hamburger bun) or 3 equal pieces; set aside. With lightly floured surface and hands, shape each dough piece into a ball. Place on prepared sheet pan (evenly separated 2-3 inches). Gently flatten each dough ball slightly with the palm of your hand. Brush dough with melted butter. Place in warm proof box to rise until double in size. Remove from proof box and very gently brush with egg wash. Sprinkle with sesame seeds*. Bake in a preheated 325 ̊ convection oven for 12-15 minutes or until golden brown. Remove from oven and let buns cool, slice to split.

*For variety: after brushing with egg wash, sprinkle bun dough with poppy seeds, caraway seeds, minced onion or finely grated cheese prior to baking.
