Double Spinach Pasta Casserole with Pesto and Fontina Cheese

I like to eat things that are healthy and not healthy for me.  Nearly a pound of spinach?  Yes please!  4 eggs plus cream?  Sure, why not!  Veggie pasta?  Definitely!  Gobs of ooey, gooey, cheese?  Why, absolutely!  If you like a good balance in your diet as well, then this recipe is for you.  And if you need to get some green food into your belly, make this ASAP.  I followed this recipe here, but used veggie pasta instead of spinach (also had zucchini in it) and fontina cheese instead of asiago.  I also doubled the recipe and it fed over 10 adults, WITH leftovers.  It was delicious... hearty, bright (the pesto added a lot of depth) and everything you would expect from a healthy/indulgent meal.
