Preheat oven to 350 F/180 C. Line a 9-inch/2.5 L square baking pan with parchment paper and grease lightly.
Whisk flour and sugar together in a large bowl and combine with the oats, apricots, cranberries, raisins, almonds, coconut, sunflower seeds, chocolate chips, cinnamon and salt. Whisk the egg with the vegetable oil, corn syrup, orange zest, orange juice and vanilla, and pour over the dry mixture. Stir until well mixed.
Firmly press the mixture into the prepared pan and sprinkle with the sesame seeds. Bake on the middle rack of a preheated oven until golden on the edges, about 20-25 minutes. Remove from oven and cool completely in the pan on a baking rack.
Run a knife around the edges of the pan. Flip carefully onto a cutting board, removing parchment paper, and cut into 12 bars. Bars will keep in an airtight container for 3-4 days.
