For the Enchiladas:

1. Bring a large pot of salted water to a boil and cook the chicken breast until it is no longer pink inside, about 15-20 minutes. Using two forks, shred the chicken and set aside to cool.
2. Preheat your oven to 400°F and spray a small baking dish (mine was 6x8) with cooking spray, set aside.
3. Spray a small, non-stick, frying pan with cooking spray and heat on high. Once hot, turn down the heat to medium/low and slowly pour 1/2 cup of liquid egg whites in, covering with a tight fitting lid. Cook until the top of the whites are just set and slightly bubbly (about 2-3 minutes). Remove the lid, carefully flip the egg whites and cook for an additional 2-3 minutes, or until the “tortilla” is cooked. Slide onto a plate and repeat with the remaining 1 1/2 cup egg whites.
4. While the egg whites are cooking, heat the 1/2 Tablespoon oil in a large pan on medium/high heat. Cook the chopped onion and garlic until soft, about 1-2 minutes. Stir in the blended tomatoes, salsa, chili powder, cumin, paprika and red pepper flakes, if using. Season to taste with salt and pepper.

To Assemble:

1. Take one egg white “tortilla” and place 2 Tablespoons of the tomato sauce in a line along the bottom portion. Top with 1 Tablespoon of the thawed corn and 1/4 cup of shredded chicken. Roll up tightly and place in the prepared baking dish, securing with a toothpick if needed. Repeat for the remaining enchiladas.
2. Pour the enchiladas sauce evenly over the dish and top with the grated cheese.
3. Bake until the cheese is melted, 8-10 minutes.
4. While the enchiladas bake, add the avocado and Greek yogurt into a small food processor, and blend until well combined. Season to taste with salt and pepper.
5.  Serve the enchiladas hot with the avocado crema and cilantro.
