This low calorie pasta is just 161 calories per cup, thanks to Fiber Gourmet Pasta. You can purchase it online (link below) or find it at your local grocery store. And if you are looking for more pasta options, see above in the ingredient section. I have also included some protein add-ins above in the ingredient section, should you want to boost the protein in this skinny pasta recipe. Special Tip: I really do recommend making your own marinara sauce. It's so much yummier than store bought. But most importantly, it's 1/2 the calories and sugar than store bought.
