Cube the chicken cutlets/tenders. Put into a bowl (or a baggie) and add one tablespoon of the olive oil and 1 tablespoon of the Italian Seasoning and a sprinkle of salt and pepper. Coat the chicken.

Add the minced garlic and saute on medium until fragrant - about 4 minutes.
Add the chicken broth, lemon zest and lemon juice, and deglaze the pan scraping any bits stuck to the bottom of the pan with a wooden spoon.
Add the heavy cream, and tomato paste.
Add the sundried tomatoes and stir until fragrant, about 2-3 minutes.
Add the kale and cook until softened on medium-low. Make sure to stir often as to not burn the garlic or tomatoes.

Add the other 1 tablespoon of Italian Seasoning and saute for a few minutes. Add more chicken broth if needed.
Add the parmesan cheese.
