Then, add the onion, carrot, spices, and breadcrumbs. Blend again until you have a crumbly mixture. Stop and scrape down the sides as needed. Add aquafaba and blend for a few more seconds. Don't overblend! You want to have some texture. The mixture should stick together when pressed, but should not be wet.
½ cup yellow onion, ½ cup carrot, 1 teaspoon ground cumin, 1 teaspoon sweet paprika, 1 teaspoon garlic powder, ½ teaspoon ground coriander, ½ teaspoon salt, ¼ teaspoon ground black pepper, ¼ cup whole wheat breadcrumbs, 3 tablespoons aquafaba
