Roast the sweet potatoes. Make multiple small slashes in each of them with a knife. Place them a baking sheet lined with parchment paper and bake for 45-55 minutes at 425 F. Set aside to cool.
For the chickpeas, add 1 tbsp avocado oil to a medium saucepan on medium heat. Add onions, stir until translucent, and then add garlic and ginger. Continue stirring for 1-2 minutes.
Add all the spices except for garam masala and amchur. Mix well for 1 minute.
Add the tomatoes and salt. When the tomatoes and spices have incorporated together and sit in the center of the pan, add the chickpeas.
Cook the chickpeas for about 10 minutes, adding a little water if they start to dry out. When they are done, finish with garam masala and amchur.
Blend the chutney in a food processor. First, blend all ingredients except for water and lime juice. Then add lime juice and a little water at a time until you are at your desired texture.
For the raita, simply mix together the ingredients in a small bowl.
To assemble the stuffed potatoes, slit the sweet potato down the center. Open it up and spoon out some sweet potato flesh to make room for the filling. Stuff it with chickpeas, green chutney, raita, and onions. (Tip: when you get to the bottom of the sweet potato, you might want to add some more chutney and raita.)
