The Health Benefits of Zucchini

Okay, can we just talk about zucchini for a minute? I feel as though it doesn’t get as much love as it should. ๐ Here are a few fun facts for you-
Zucchini contains only 17 calories and 3 grams of carbohydrate per cup!
The highest levels of antioxidants are found in the zucchini’s skin, so do not peel!
Zucchini is rich in both fiber and water, which promote healthy digestion!
You can consume 40% of your RDI for vitamin A in just one cup of zucchini, which can support good eye health!
How to make Zucchini Pizza Casserole
First, preheat oven to 400 degrees.
Grate the zucchini, place it in a colander, and drain out the excess moisture with the back of a spoon.
In a mixing bowl, combine the zucchini, eggs, parmesan cheese, black pepper, onion powder, and 1 teaspoon of the Italian seasoning. Press the mixture into a lightly greased 9×13 baking pan and bake for 20 minutes.

Meanwhile, heat the oil in a large skillet over medium heat. Saute the onion and bell pepper until soft and the onion is translucent. Add the garlic and cook for another minute.
Add the ground turkey and cook thoroughly. Stir in the marinara sauce and 1 teaspoon of the Italian seasoning.
Remove the zucchini crust from the oven and spread the sauce mixture evenly on top.

Then sprinkle on the mozzarella cheese, as well as the remaining 1 teaspoon of Italian seasoning. Bake for an additional 20 minutes.

Enjoy!
