Creamy Sweet Potato Bake

I made this meal in my classic method - "I have these three ingredients I need to use...what can I make?"  I looked at a few recipes and created a plan... It turned out fabulous!  The recipe perfectly creamy and savory and brings the natural sweetness out of the sweet potatoes.

Ingredients:
1/2 C sweet onion, chopped
2 Tbsp olive oil
1 clove garlic
salt & pepper, to taste
1 tsp chicken bullion
2 large sweet potatoes, thinly sliced
2 C cooked, shredded chicken breast
1 1/2 C cooked brown rice
1/4 C flour
2 C heavy cream (or milk)
8 oz fresh spinach, chopped
2 C shredded Swiss cheese

Directions:
1.) Saute onion with olive oil and garlic.
2.) Season as desired with salt, pepper, and chicken bullion.
3.) In a separate pan (covered), saute sweet potatoes with olive oil until tender.
4.) When onions are tender, add shredded chicken and rice to pan.
5.) Mix flour into onion and chicken mixture.
6.) Slowly add 2 C cream into the mixture.
7.) Heat until starting to boil.
8.) Add spinach and stir just until wilted.
9.) Spread half of the chicken mixture on bottom of 9x13" pan.
10.) Place one layer of sliced sweet potatoes on top.
11.) Shake 1 C of cheese on the sweet potatoes.
12.) Repeat layers (chicken mixture, sweet potatoes, cheese).
13.) Bake at 325 degrees for 15 minutes or until cheese is melted.
