A favorite switch that I've made is mixing traditional pasta noodles with vegetable noodles. I don't mean the packaged veggie-infused pastas, but spiralized zucchini and carrot. I have to use two pans because the veggies cook up in just a few minutes. I make the pasta noodles as usual, but only use half of what I used to. I saute the veggies in another pan with a little olive oil. Once both sets are done, I mix them together and top with my sauce. It's a great way to enjoy pasta with less guilt and more veggies. It's a win-win.
