Preheat oven to 425°F and line a baking sheet with parchment paper.
In the bowl of a food processor, combine chickpeas, ½ cup breadcrumbs, flour, egg, lime juice, sesame oil, garlic powder, onion powder, salt, cumin, cayenne pepper, and black pepper. The mixture should stick together like a ball.
Add remaining ¼ cup of breadcrumbs to a shallow bowl. Roll two tablespoons of chickpea mixture into a ball and flatten into a ½-inch thick disc (I used cookie scoop). Toss in breadcrumbs and place on prepared baking sheet. Repeat with the remainder chickpea mixture. Spray chickpea bites with nonstick spray and bake until golden brown, 20-25 minutes, flipping halfway through.
Meanwhile, make the avocado dip. In a medium bowl, combine avocado, lime zest and juice, garlic powder, and onion powder. Combine and season with salt and black pepper, to taste.
