Place all ingredients in a blend and blend for approximately 20 seconds, until just mixed.
On medium heat, melt 1/2 tbsp of butter. Once it just starts to bubble, add enough egg white mixture so that it's just covering the pan (like a crepe).
Cook until the edges begin to crisp up (about 2-3 minutes), and then carefully flip to cook the over side. Repeat until all egg white mixture is used up.
In a medium bowl, whisk together eggs and milk. Add 1/2 tbsp of butter to a pan on medium heat and cook for approximately 3-5 minutes. Set scrambled eggs aside.
In a medium sized bowl, add chicken and the rest of the ingredients. Mix together well and cook on the stove on medium heat until chicken is cooked all the way through.
Add fajita mix and scrambled eggs to the tortilla's. Top with salsa, avocado, ranch dressing, and lettuce. Enjoy!
