Chicken, Potato, and Leek Cheddar Casserole, TexMex Style

Jump into this fall weather feet first ,with this warm and hearty casserole, embellished with some cool summer flavors and colors.  Lots of fresh herbs potatoes, leeks, and quick marinated chicken form a outstanding profile, while the tomatoes and avocado add even more B vitamins , lycopene, (tomatoes) plus heart healthy unsaturated fats and the ability to help the body absorb more of the nutrients from other ingredients in the dish (avocados).
Assembly is easy and this dish may be prepped ahead of time and baked when needed.
The casserole servings rest on a bed of tortilla rounds, adding a savory crunch and more texture, pairing well with the fresh salad atop.
The family received this dish very well and I look forward to preparing it again soon, real soon!
