Put everything except the pork, salt, pepper, and olive oil in the slow cooker.
In a large skillet over medium-high heat, brown the cubed pork in the 2 tablespoons of olive oil. Sprinkle with salt and pepper.
Place the pork on top of everything else in the crock pot. Do NOT stir it.
Cook until the pumpkin is tender-- about 2-3 hours on high or 4-5 hours on low. Remove the pork from the crock pot.
Using an immersion blender, blend everything else all together until it’s smooth. If you don’t have an immersion blender, you can just blend it in a regular blender in smaller batches and then return the blended stew to the slow cooker.
Return the pork to the crock pot and stir it the stew base. Allow it to continue cooking for another hour on high or another couple of hours on low.
Serve with rice, naan, fry bread, or crusty rolls.
