Preheat the oven to 350F. Spread the sesame, sunflower, pumpkin and sliced almonds on a large baking tray. Bake at 350F for 15 minutes or until lightly toasted. Remove and set aside to cool. Grease a 13" x 9" baking pan and set aside.

In a large pot, melt the butter over low heat. Add the marshmallows and continue to stir until they are completely melted. Remove from the heat and stir in the vanilla extract, then add the toasted seeds and nuts, dried cranberries and rice krispies and mix well to combine.

Empty the mixture into the greased baking pan and use a greased spatula to spread evenly and then press and compact the mixture down. Set aside to cool, then cut into 32 bars (or whatever size and amount bars you would like). Store in an air tight container or bag.
