Spaghetti Squash Casserole

The first recipe on this page was my inspiration for today.

1/2 of a large spaghetti squash, cooked and shredded
4 T butter
1 onion, chopped small-ish
4 cloves garlic, minced
about 12 oz crimini mushrooms, cleaned and sliced
about 8 oz fresh spinach, roughly chopped
salt, pepper, and dry parsley to taste
2-3 cups shredded mozzarella

Melt the butter in a large skillet.
Saute the onion for a couple minutes (long enough to mince garlic), and add the garlic.
Continue to saute (long enough to slice the mushrooms) and add the mushrooms.
Continue to cook (long enough to chop the spinach, and let the mushrooms cook down to make some room) and add the spinach.

Add salt, pepper, dry parsley, and spaghetti squash.

 Add half of the mozzarella, and stir it in.
Put it all in a casserole dish (mine was between 8x8" and 9x13", and I sprayed it with olive oil first).
Put the rest of the mozzarella on top.
Bake it for about 15 minutes (or more if the spaghetti squash was cold) at around 350F.
