Using a fork, poke some holes into each sweet potato, and bake them for 45 minutes at 200ºC.
Meanwhile, heat the oil in a pan over medium heat, and add the onion and bell pepper. Sauté until soft.
Add the beans, cook until heated through, then add the spice mix.
Mash the avocados in a small bowl and mix in the lime juice.
Check the sweet potatoes after 45 minutes, they should be soft. Remove them from the oven, make a slice along their length, and open them up to make space for the beans.
Spoon the beans onto the sweet potatoes, followed by the salsa, vegan cheese, avocado and spring onions.
Serve immediately :)
