Finely chop the onion and carrot. Dice the potatoes into small, bite-sized pieces (about 1/4 to 1/2" square). Slice then roughly chop the bell pepper.
In a large pot over medium, heat the ghee. Add the carrots, onion, and potatoes, sautéing until they begin to soften (about 8 to 10 minutes). Stir in the bell pepper, and continue to cook until tender, about 3 to 5 minutes.
Add the spices and herbs, stirring into the vegetables until fragrant (1 to 2 minutes). Stir in the bone broth, and bring the soup to a boil. Reduce to a simmer, cooking until all of the vegetables are soft.
Use an immersion blender to blend the soup about half of the way, leaving whole pieces of vegetables. You could also transfer half of the soup into a blender or food processor, pulse until smooth, then return it back to the pot.
Add salt & pepper to taste, and adjust the seasonings to your liking. Give it a final stir & serve hot!
