I wish I could take credit for this brilliant idea, but unfortunately I can't. I didn't really follow a recipe, but the inspiration did come from this recipe.
First, cut open your spaghetti squash...easier said than done, I know!
Scoop out the seeds and gunk. Don't forget to roast them just like pumpkin seeds - set them aside in a bowl of room temperature water for later.
Drizzle with olive oil or spray with PAM and sprinkle with salt and pepper.
Bake (flesh side down) at 350°F for 30-40 minutes or 400°F for 15-20 minutes if you're impatient like me. Using a fork, scrape the strands out from stem to stem. Dry the strands really well.
Put some of the strands back into the bottom of the squash "shell" - or a casserole dish - and top with a layer of sauce (a layer of cheese or other veggies like a noodle lasagna would be good too). Continue layering the squash strands and sauce until full. I used homemade meat sauce with ground chicken and chicken sausage, but any tomato sauce will work just fine.
Sprinkle with some shredded Mozzarella and bake at 400°F for another 10-15 minutes until the cheese is nice and brown.
Slice it in half and enjoy! Yummy!
