Baked Chicken and Zucchini Casserole

Baked chicken and zucchini casserole is a delicious combination of zucchini, chicken, tomatoes, mushrooms, and spices. You can made the entire dish up in about an hour. It comes together quickly but the longest part is baking. What I usually do is make it up the night before, cover it, and place it in the fridge. The next day before dinner, pop it in the oven and a few minutes later dinner is served. If you are working and your oven has a timer, the entire process becomes even easier.

As always, there are a few pointer to making the recipe. First thing that does have to be noted is not to add too much of the undrained diced tomatoes. I find just a little over a cup or about 400 ml is lots, otherwise the dish will be too watery. I learned this from personal experience. I use boneless skinless chicken breasts as they are so easy to work with and healthy, but you can use the cut of chicken of your choice. Be sure, however, to adjust the baking time accordingly.
