The heat came on in our apartment this morning – gasp!

The wind is violently blowing rain and leaves atourwindows and the sky is black and angry. It’s pretty stormy out there and it couldn’t be more obviousthat summer has officially left Brooklyn.

Okay, I’ll admit I’m a little sad to saygoodbye to hot, sunny days but I’ll also admit to loving fall withits cooler temperatures andvibrant colors. I think every season has something wonderful to offer and to me fall means more quiet evenings at home, snuggling on the couch with my lovely husband and kitty.

It also means the return of some of my favorite tv shows (I’m totally obsessed with Nashville these days!) and hearty, comforting dishes like this easy spaghetti squash alfredo recipe.

The toppings I have chosen for this spaghetti squash alfredo recipe can be swapped for other herbs,or you can add a squirt of hot sauce, or another condiment of your choice. As I previously mentioned, spaghetti squash is really versatile.

I’m using a mix of chives, scallions and parsley because I love the combination of light, fresh and hearty. I then finished the dish by topping it with about a tablespoon of freshly grated parmesan cheese for more creaminess and akick of umami. Scrumptious!
