Preheat oven to 325°. Stir together melted butter, honey, brown sugar, vanilla, and salt in a large bowl. Add oats, pecans, wheat germ, and sesame seeds, and stir until mixture is evenly coated. Spread oat mixture on a lightly greased 15- x 10-inch jelly-roll pan. Bake 25 to 30 minutes or until toasted, stirring every 10 minutes. Spread granola onto wax paper, and cool completely (about 30 minutes). Stir in chopped dates. Store in an airtight container at room temperature up to 3 days, or freeze up to 6 months.
