Make 2-3 9x13 pans
Layer in this order starting with the tomato sauce.
When you put in the spinach and turkey break it up with your hands to help with clumping when it's done.
Mix it all up a little so that the water can be soaked by the quinoa but the pot also creates steam so it doesn't have to be perfectly covered.
Set your pot for 40 minutes and let it go.
When it's done stir it up to combine everything and spread evenly into 2-3 pans.
You can allow this to cool and then freeze it. When you are ready to use it just thaw it and cook at 350 for 25-35 minutes.
I also like to top mine with another 14oz can of tomato sauce and a can of diced tomatoes.
