1/2Red Onion,skin removed and cut into 1/4" slices crosswise
1/2cupRice Vinegar or Apple Cider Vinegar
To make the Quick Pickled Onions
Place the sliced onions in a small strainer and pour a few cups of boiling water over the top.
Combine all the remaining ingredients in a glass jar or a small bowl, stirring to dissolve the sugar and salt.
Add the onions to the pickling liquid and let sit at room temperature for 30 minutes to 1 hour. Placing in the refrigerator will stop the pickling process.
To make the Avocado Crema
Blend all of the crema ingredients until smooth. Cover tightly with plastic wrap if not using right away.
To make the Tacos
Heat a cast iron skillet over medium-high heat with a drizzle of canola oil. When the skillet is hot, add the shredded pork and let it start to get crispy before stirring. You just want to warm it through and get the edges crispy.
Warm the tortillas in a skillet or over a gas flame on your stove. Spoon the avocado crema onto the tortillas, followed by the pork, pickled onions, cilantro and a lime wedge.
