Get a pot of water boiling for the pasta and heat up the grill for the chicken. I oiled the chicken and used Italian seasoning . Also i only used half of the chicken you see in the picture . Cook chicken and pasta when ready .

Melt butter in a large pan and put your diced onions inside. Saute for a couple minutes. Add garlic and saute till fragrant

Sprinkle the flour over the onions and continue stirring four a couple of minutes.

Slowly pour and stir milk in. Continue to stir until it starts to heat up and thicken.

Add your mozzarella, parmesian, and cream cheese. Stir until all melted and conjoined. Couple of minutes

Chop your chicken and artichokes. Throw penne, artichokes, and chicken in pot and fold in, continue to heat through

Once you have it all mixed together and heated through, add spinach. I used a can of spinach which made it look like the actual dip you are used to seeing. Just really drain it well to get all the liquid out. If you want it to look not as green, use a couple of handfuls of fresh spinach and wilt it down a couple of minutes in the pot. Its a much cleaner look.
