This is a pretty quick and yummy weeknight meal. Just boil the potatoes, while they are boiling prepare the rest of the ingredients and once the potatoes are done you can assemble and eat!
The mashed potato filling is really, really tasty. I seriously had to stop myself from eating it all while I was assembling the tacos! It's very fresh tasting, creamy and tangy, with a slight spicy kick from the Serrano. If you're serving these to kids, feel free to omit the chili, they will still be delicious!
