Cut pork chops into small, bite-sized pieces. In a bowl, mix together corn starch, oil, cumin and 1 teaspoon black pepper until smooth, like a runny paste. Add pork to mixture and set aside to marinate for 30 minutes.
While pork marinates, wash cilantro and pluck whole leaves from stems, about 3/4 cup worth. Place whole cilantro leaves in a bowl. Thinly slice 1 red onion and add to cilantro, creating a salad. (You can adjust cilantro/red onion ratio to taste.) Add a dash of black pepper, one tablespoon of vinegar and one tablespoon of olive oil, toss to coat and set aside.
After pork has marinated, cook it in batches. Add a teaspoon of olive oil to a non-stick sauté pan and place over medium-high heat. When oil comes to temperature, cook half the pork pieces (without removing the marinade). Cook until the outside of the pork pieces are brown and a crust has formed and the inside is cooked through, about 5 minutes per side. If needed, add more oil to the pan, and then cook the second half of the marinated pork. Once finished, sprinkle cooked pork with salt to taste.
To assemble tacos warm tortillas according to directions on the package. Take one tortilla and smear a teaspoon of sour cream down the middle. Top with 7-8 chunks of pork. Atop pork, place a spoonful of salsa, then top with cilantro red onion salad, a teaspoon of corn kernels and pinch of cheese. Fold over to enjoy!
