Set your oven to 180°C (fan) and put baking paper on a tray. Scrub the sweet potatoes well and poke a few holes in them with a knife so steam can escape. Place them on the lined tray and bake until tender, about 40 minutes. Use a fork to check softness.

Around 10 minutes before the sweet potatoes finish baking, warm a small splash of oil or water in a skillet on medium heat. Toss in the chopped onion, mushrooms, and pressed garlic. Stir the mixture until the mushrooms soften, release their liquids, and turn golden. Mix in the spinach, tahini, nutritional yeast, and a bit of salt and pepper. Let the spinach wilt and everything meld into a creamy mixture. Squeeze in lemon juice and sprinkle a dash of cayenne if you'd like it spicy. Stir again.

Take the sweet potatoes out of the oven and leave them to cool slightly. Slice each one down the middle, then fluff the insides with a fork to make room for the filling. Stuff the potatoes with the creamy veggie mixture, ensuring they're nicely packed.

Serve hot. It works great as a cozy meal or a light snack.
