Wash the sweet potato then pierce it a few times with a fork, heat on max heat in the micro for around 5 min (time varies with your micro and the potato you use). You know when it is ready if a thin stick can easily pierce the whole potato.

While the potato is cooking you can chop the onion and fry it

Take the potato out of the micro (careful, it is hot!) and cut in half lengthwise

Scrape out the potatoes with a spoon and place in a bowl

Mash the potato roughly

Rinse the beans and spinach

Heat up a pan on medium heat with some butter

Add one tortilla then spread shredded cheese on it, then add the filling on half the tortilla. Squeeze out a few drops of lime at the end.

Fry until tortilla starts to get some color, then turn the empty side over the filling and transfer to your plate. Cut in 3 equal pieces with a knife or a pizza cutter.
