In a smaller mixing bowl, whisk together the almond butter, honey and vanilla extract until well blended.
In a mixing bowl, combine the contents of the food processor with the oats, orange zest, cinnamon and salt. Whisk to combine.
In a medium skillet over medium heat, toast the pecans and pepitas, stirring often, until they are fragrant and the pepitas are starting to make little popping noises, about 5 minutes. Transfer the toasted pecans and pepitas to a food processor. Add the cranberries and then run the machine for about 10 seconds, until the nuts and cranberries are all broken up. (If you skip the food processor step, your bars will be more difficult to slice through and more likely to crumble at the edges.)
Line a 9-inch square baker with two strips of criss-crossed parchment paper, cut to fit neatly against the base and up the sides. The parchment paper will make it easy for you to slice the bars later.
