Boil the sweet potatoes in a large pan of salted water until soft.
Whilst the potatoes are boiling, heat the avocado oil, and saute the zucchini, onion, celery, carrots and garlic until soft. Add the ground beef, tomato paste, and all seasonings and cook until browned.
Drain and mash the potatoes, then spread on top of the ground beef mixture. Top with the paprika, and bake in the oven for 15 minutes.10
