I love spaghetti. I love spaghetti <— thiiiiiiiiiiiiis —> much. Spaghetti is a weekly staple. And when I’m having one of those weeks — you know what I’m talkin’ about — sometimes it’s an all-the-days-that-end-in-y dinner.

In the winter, it’s spaghetti with marinara sauce. (Sometimes I get fancy and saute some mushrooms, too.) In the summer, it’s a cold spaghetti salad that I love so much I could eat on every day that has a “y” … for dinner and lunch.
