Preheat oven to 350ºF. Spread oats in a 9x13" metal baking dish and toast for 20 minutes, stirring every 5 minutes.
While oats are toasting, melt butter in the microwave for 30 seconds on high power. Let cool to room temperature.
When oats are deeply golden brown and nutty smelling, spread them out over a cold baking sheet to cool them quickly. Run the hot baking dish under cold water to cool it down, too, then line it with parchment paper.
In a large bowl, combine cooled oats salt to combine, then stir in condensed milk, cooled butter, seeds, dried fruit and chocolate chips. Dump the mixture into the parchment-lined baking dish then press it down into an even layer (lightly moisten your hands to make it easier). Bake for 15 minutes until edges are a shade darker. They will firm up as they cool. If overbaked, they become crunchier granola bars, which are still tasty.
Lift the whole slab out of the pan by the overhanging parchment paper and cool on a wire rack, then slice into 18 bars.
