Butternut Squash Pizza

I was reading my favorite cooking/nutrition blogs a few days ago, and came across this idea for a recipe. I wish I could give credit, because these are REALLY good. I did add caramelized onions and tomato sauce to the recipe, but the idea to use the squash this way wasn't mine. Anyway, this is a must try recipe, it is really terrific!

Butternut Squash Pizza

1 butternut squash with the longest neck possible
1 lb of bulk sweet Italian sausage (no nitrates added, no high-fructose corn syrup)
1 block of feta cheese
1 large onion
olive oil, salt and pepper
favorite tomato sauce

Pre-heat oven to 375. Peel butternut squash and cut into 1/2" disks, be careful to make them the same thickness so they cook evenly. Rub each disk with olive oil, salt and pepper. Bake on a cookie sheet for 20-25 minutes until you can easily pierce with a fork. Meanwhile, brown sausage in a skillet. Slice onion into very thin slices and saute them in a little olive oil (or bacon grease) while the sausage is a different skillet. Cook the onions on medium  heat for 20-30 minutes.

Remove butternut squash from the oven and switch the oven to broil. Assemble the pizzas by placing a bit of sausage on each disk, top it with a bit of onion and then the feta cheese. Place under the broiler for 4-5 minutes until feta starts to brown. Serve on top of some tomato sauce. It'd be great with some fresh basil on top, but I'm not sure if butternut squash and basil are ever in the same season? Anyway, this was a huge hit for our family and I think I'll hide the leftovers!
