IT'S ANOTHER LEFTOVER RECIPE!
What is it about the laws of the universe that are super duper intent on NEVER allowing you to make the correct amount of pasta to sauce? It's a thing, right?
So this is what you do: since you know this is going to be happening, err on the side of extra pasta, not extra sauce. Then you make this cold salad all summer long with your extra noodles. The dressing is what makes it, and you can use any veggies or pasta type that you like. Toss it all together, lunches for days.
