Heat oil in a large pot over medium heat and once it's hot, add the onion and cook for 7 minutes, until soft and translucent.
Add the garlic and cook for an additional 3 minutes, stirring often to prevent burning.
Add the frozen cruciferous scraps, broth, nooch, and spices to the pot.
Bring everything to a boil and then reduce to a simmer, allowing it to cook for at least 30 minutes.
While the soup is simmering, prepare the (optional) crispy chickpeas. Drain and rinse a can of chickpeas, and then add them to a bowl with the spices. Stir to evenly coat the beans in the seasoning.
Add the beans to the basket of an airfryer and cook them for 15 minutes at 400°, mixing halfway through. When they're done, put them in a bowl and set aside until the soup is done.
When the cruciferous veggies have softened, turn off the heat and add the lime juice.
Carefully puree the soup using an immersion blender.
Garnish & enjoy!
