In a pan over med heat add butter til melted, meanwhile season chicken with salt,lemon pepper,garlic powder and onion powder. Put into pan and cook until golden brown on both sides. Then place in oven at 350 for about 25 mins or until it runs clear.
When chicken is almost done in oven start ur sauce. In a pot over med-low heat add feta cheese,Parm cheese,Lemon juice,salt,milk and ranch dressing,Mix together, stir til cheese is melted.
Put water in a pot for ur rice and cook as directed.
When chicken is done take out of oven and set aside keep warm by putting tin foil over top. In a skillet on med heat add a little butter and then ur spinach and over stiring around sometimes until it welts down then take off heat.
To plate what I like to do is put some rice down then add chicken to the top and then the spinach and then the feta sauce.
