Place a medium to large pot over medium-high heat.
Pour oil, and once it's ready, add garlic and onion.
Sauté until the onion softens.
Add chickpeas, sweet potato, and chopped carrot- mix and combine.
Pout the stock and add the dried rosemary, salt, and ground black pepper.
Cover with a lid and bring to a boil.
Lower the heat, then continue simmering until the vegetables are tender.
Transfer about two cups of chickpeas, sweet potatoes, and carrots into a bowl and use an immersion blender to puree them.
Add the pureed portion back into the pot --- and mix to combine.
Taste and adjust the seasoning with salt and pepper; place the lid back on.
Continue simmering for two more minutes, then take your sweet potato and chickpea soup off the heat.
Transfer into serving bowls and garnish with fresh parsley, if preferred --- enjoy!
