Prepare Chickpeas: In a large bowl, mash the chickpeas with a fork or potato masher until mostly smooth, leaving a few chunks for texture.
Mix Ingredients: Add breadcrumbs, nutritional yeast, garlic powder, onion powder, smoked paprika, olive oil, salt, and pepper. Stir in the plant-based milk and Dijon mustard until the mixture is well combined and holds together.
Form Nuggets: Shape the mixture into small nugget-sized pieces, about 1-2 inches wide.
Cook: Preheat the oven to 400°F (200°C). Place the nuggets on a parchment-lined baking sheet, spray lightly with olive oil, and bake for 15-20 minutes, flipping halfway through, until golden and crispy.
Serve: Enjoy your chickpea nuggets with your favorite dipping sauce like vegan ketchup, BBQ sauce, or tahini dressing.
