How often do you find a recipe that is low-carb and high-protein, delicious, and actually healthy? This Low-Carb Mediterranean Roasted Vegetable Penne Pasta is all of those! In addition, it is easy to make and quick to get on the table. Here is the scoop!

The dish starts with healthy ingredients such as bell peppers, onion, zucchini, and olive oil. They get roasted to perfection.

A low-carb pasta recipe needs low-carb pasta. In this case, it is Great Low Carb Pasta - Penne with only 7 grams of net carbs. You can cook it just like you cook regular pasta, but skip most of the carbs.

Then, toss everything in a delicious and simple sauce made with more heart-healthy olive oil, along with tasty parmesan cheese and Italian herbs. Everything comes together beautifully without much effort. You can serve it with extra parmesan cheese and fresh or dried herbs if you like.

With 12 grams of protein per serving of pasta, this dish already has plenty of protein. But if you are on a high-protein diet, you can definitely add more. Try baking salmon, shrimp, or chicken when you roast the vegetables if you want to add more protein. Or, you can try it with tofu to keep it as a meat-free recipe.
