Lightly grease a 9x13 inch baking pan and set aside.
In a large bowl, mix together the oats, rice cereal, pecans, sesame seeds and raisins.
In a large saucepan, over medium heat, bring the honey and salt to a boil. Boil, stirring occasionally, for 5 minutes. It will bubble up a lot so make sure your pot is big enough and keep an eye on it.
Remove the honey from the heat and pour it over the oat mixture. Stir quickly with a greased wooden spoon or silicone spatula until everything is well coated and then press the mixture into the prepared pan.
Cover the bars with some greased wax paper and use a flipper to press it down firmly into the pan.
Let the bars cool completely before slicing. They will keep for up to two weeks in an airtight container at room temperature. They are a bit sticky so put wax paper in between layers, or wrap the bars individually.
