Blend: Add 1 medium yellow onion and 2 cloves garlic to a food processor and blitz until broken down. Add in 2 cups walnuts, 1 15-oz can black beans, 1 packet taco seasoning, and 2 Tbsp tomato paste. Pulse just until evenly combined (it's okay if there are still some bigger pieces).
Bake: Spread mixture onto a parchment-lined baking sheet in as thin of a layer as possible. Bake for 15 minutes, then use a spatula to flip everything overn and break up the big chunks. Return to the oven for another 15 minutes. It should be browned and crispy at the edges when finished.
Serve warm anywhere you would use taco meat!

Notes
Store any leftovers in an airtight container in the fridge for up to 5 days. You can also freeze everything for up to 2 months in a flat layer in a reusable bag or container. Reheat in a skillet or oven for the best texture.Can I use raw walnuts? Yes! Raw walnuts work best here. Toasted ones can be a bit too bitter or oily, and we’re baking them anyway.Can I make this in a skillet instead of the oven? Yes! Use a large non-stick or cast-iron skillet over medium heat. Stir frequently and cook until browned and dry. It won’t get quite as crispy as the oven but still tastes great.
