Boil a pot of water and cook the fettucine according to package instructions. You don't need to use fettucine just like I did, but fettucine has a shape that blends nicely with the veggie "noodles" so my kids don't notice they're eating as many vegetables.
Use a vegetable peeler to peel the zucchini and the carrots into long "noodle-like" strips.
Heat the olive oil over medium in a skillet or saucepan. Add the minced garlic and cook the garlic for about a minute until fragrant.
Add the zucchini and carrot and saute for about 3 more minutes. It might be helpful to turn the heat down to medium-low, put the lid on the pan or skillet and steam the vegetables to help them soften up a little faster.
Stir in the salt and pepper.
Stir the vegetable mixture into the cooked fettucine.
Stir in the chopped basil, chopped walnuts and Parmesan cheese just before serving.
