Begin by marinating the meat. Chop your boneless pork chops until you have small pieces, about pea-sized. This will allow the marinade to penetrate the meat very well. Add them to a large bowl.
Add all the rest of the carnitas ingredients into the bowl and mix very well. Cover with plastic wrap and place in the fridge for at least 4 hours, as long as 48 hours.
When you are ready to cook, preheat the oven to 350 degrees F. Lay out your tortillas on a baking sheet. Spray both sides with olive oil spray.
Place in the oven for 5 minutes. Flip the tortillas carefully and place them back in the oven for another 5 minutes. Remove from the oven and set them aside.
Next, make the Avocado Crema. Add all ingredients into your blender and blend until smooth and creamy. You want a thin, runny consistency so add a little water if needed for a pourable sauce.
Finally, brown the carnitas. Place a large skillet over medium-high heat and add the pork. Allow it to sizzle and brown for 8-10 minutes, lowering the heat if necessary. You want deep caramelization on the meat for optimal texture. The meat will sizzle at first, then start to steam in its juices.
Once the moisture evaporates, after 4-5 minutes, the meat will begin to brown deeply. Keep an eye on it and do not walk away during this process.
Once the meat is browned, remove it from the heat. You may need to skim off some excess oil from the cooking process.
When you are ready to assemble, spoon about ⅛-¼ cup of meat onto each tostada. Top with cheese, red cabbage, crema, and cilantro. Serve with additional lime wedges.
