I needed a way to jazz up some spaghetti squash when I was running out of marinara sauce and just started pulling stuff out of the fridge. It came out great. The amounts are approximate and you can adjust to suit your own style/taste. Garlic and olives would probably be great in this too, even capers. What the heck, throw it all in.

The squash can be cooked in the microwave for 12 minutes instead of the oven if desired.

not being the biggest fan of spaghetti squash and wanting to find a different used for it I tried this recipe even with no rating. it turned out fantastic! my whole family enjoyed it. It was very flavorful and not Bland at all. I use a whole can of our favourite pasta sauce & some fresh garlic and mixed it in with the squash. I then layered it like the recipe said starting with a third of the squash then onions and spinach and cheese. then repeated the layers until all the ingredients were gone. this will definitely be a staple in our house as a healthy meatless option. my only change for next time is it I might saute the onions and spinach beforehand and add shredded cheese to the top. give it a try you won't be disappointed!!!
