Roughly chop the hazelnuts, pumpkin seeds, figs and prunes (if you want it finer, chop finely). Grate the apples. Put the flour and oatmeal in a bowl. Mix in the water, oil and the remaining ingredients, season with salt, honey and cinnamon and knead everything into a dough.
Line a baking sheet with parchment paper and spread the dough evenly. Bake in a preheated oven at 180 ° C for about 30 minutes. Cut the still warm dough into 20 portions and allow to cool.
You can store the bars in a tin can or the like using the parchment paper as an intermediate layer so that the bars do not stick together.
