Line an 8×8 or 9×5-inch baking dish with parchment paper, leaving overhang for easy removal. In a large bowl, combine oats, chopped nuts, chocolate chips, dried fruit, cinnamon, and salt. Stir until everything is evenly distributed.

In a small bowl, whisk together almond butter, honey (or maple syrup), and vanilla extract until completely smooth and creamy. If almond butter is thick, warm slightly in microwave for 15-20 seconds.

Pour the wet mixture over the dry ingredients and mix thoroughly with a spatula. The mixture should feel sticky and hold together when pressed. Add extra tablespoon of honey if too dry.

Transfer mixture to lined dish and press down firmly using clean hands or back of spatula. Press hard for bars that won't crumble when cut. Slightly damp hands prevent sticking.

Refrigerate for 1-2 hours until completely firm. Remove using parchment paper overhang and cut into desired bar sizes with sharp knife.
