Preparing the chicken for the walnut and spinach stuffed chicken
To make the chicken thin and workable cutting the chicken on the bias and pounding it thin is necessary. Cutting the chicken on the bias is not difficult at all. This technique is basically butterflying the chicken. After butterflying, just finish cutting all the way through and you end up with two pieces. You then take the two pieces and place them between two pieces of plastic wrap. Using a meat tenderizing mallet, pound the chicken so it is this but not torn. Repeat this for all the pieces of chicken you are using.
The spinach
I made the recipe with two 10 ounce bags of fresh spinach that I wilted in a pan with a little bit of olive oil. Just add two tablespoons of olive oil to a pan over medium heat and add the spinach. Place the lid on and stir occasionally. The spinach will start to wilt almost right away. Strain the spinach well after it is all wilted. The other option is to purchase two 10 ounce packages of frozen spinach and thaw and drain them. It is very important to try and get as much moisture as possible out of the frozen spinach.
Variations
The blue cheese sauce and walnuts can be substituted if you are not a fan of them. An asiago cheese sauce and pistachios would work well.
It is important to remember to place the chicken seam side down to ensure the stuffing stays in the chicken while baking. If it is baked seam side up, the chicken may open up and it may turn into a casserole.
The walnut and spinach stuffed chicken recipe can be a great meal for a large crowd and can be made the night before. We made the recipe the night before in 9 x 13 pans. We then covered them and stored them in the fridge. The sauce was made the day of the party but it could be made the night before.
