What is the nutrition like in this pizza soup recipe?

I always say, flavor comes first and nutrition comes second. I truly believe that you shouldn't have to choose between healthy food and food that tastes great! Despite tasting just as good as your favorite pizza, this soup packs in a ton of nutrition.

Garlic (Beneficial Sulfur Compounds, Manganese, Vitamin B6, Vitamin C, Selenium)

Garlic has been used in homeopathic remedies for thousands of years and is thought to reduce the risk of heart disease, high cholesterol and some types of cancer. Eating garlic may also help prevent colds and other minor illnesses.

Scientists believe these substantial health benefits may stem primarily from garlic's sulfur compounds such as allicin, diallyl disulfide and sallyl cysteine.

Bell Peppers (Vitamin A, Vitamin C, Folic Acid, Iron, Potassium, Fiber, Antioxidants)

Bell peppers provide tons of good-for-you vitamins. The combination of iron and vitamin C in bell peppers makes them particularly good for preventing anemia. Green bell peppers in particular are high in lutein, making the highly beneficial for eye health.

Onion (Vitamin B6, Vitamin C, Antioxidants, Folate, Potassium)

Did you know that the humble onion is actually packed with antioxidants? Antioxidants help protect you from free radicals that cause things like cancer and heart disease. Onions also have beneficial sulfides and polysulfides which may help protect against cancer.

Mushrooms (B Vitamins, Selenium, Copper, Potassium)

There are of course many kinds of edible mushrooms but the ones you most commonly find in the grocery store are either white button mushrooms or crimini (baby bella) mushrooms. Mushrooms are an excellent source of the antioxidant selenium as well as B-vitamins, copper and potassium.

Tomatoes (Vitamin A, Vitamin C, Vitamin E, Potassium)

Packed with antioxidants, tomatoes may help reduce the risk of several kinds of cancer. Bonus tip? Combining tomatoes with healthy fats boosts absorption of tomatoes' phytochemicals!

Olives (Vitamin E, Iron, Calcium)

The healthy fats in olives make them beneficial for heart health. Olives are also quite low carb, so great for any keto or low carb eaters. Eating olives may help reduce inflammation and support bone health.

Italian Seasoning

Italian herb blends can vary but often include basil, oregano, rosemary, sage and thyme. Each of these herbs provides substantial health benefits. 

A significant source of Vitamin K, basil may also reduce memory loss, blood pressure, and depression. Simply Inhaling the scent of rosemary can improve memory, focus and mood. Thyme is thought to potentially help lower blood pressure, improve immunity and help improve your mood.

Using an Italian herb blend is a great way to incorporate these herbs regularly!

Sausage (Thiamine, Selenium, Zinc, Vitamin B12, Vitamin B6, Iron, Protein)

Sausage is probably not the first thing that comes to mind when you think of nutritious ingredients. I wanted to make sure to include it here though because the nutrition content of sausage can vary SO much!

I love Butcher Box and US Wellness Meats for all of my meat but this is never more true than for items like bacon and sausage, where grocery store brands can contain some iffy ingredients. The sugar free Italian pork sausage from US Wellness Meats would be perfect in this recipe!

Pork provides substantial amounts of thiamine, selenium, zinc, vitamin B12, vitamin B6, iron and, of course, protein.

Is this a good keto meal prep recipe?

Yes! We developed this Italian sausage pizza soup recipe for our Prep Dish low carb meal plans, which are designed for low carb / keto meal prep.

I recommend making the entire recipe during your weekly meal prep session. It doesn't take long and, like most soups, it is every bit as good leftover.

What are some other high protein soup recipes?

Turkey Taco Soup: In the same way that my pizza soup recipe mimics the classic flavor of pizza, my turkey taco soup has all of the delicious taste of tacos, but in a healthy soup form. This one is always a favorite with kids and adults alike!

Chicken & Cauliflower Chowder: Both chicken and bacon contribute to the high protein content here. Coconut milk lends all of the creaminess characteristic of chowder, without any dairy.

Thai Curry Soup Recipe: One of my personal favorites, this Thai curry soup has plenty of protein from the chicken and plenty of flavor from cilantro, ginger and Thai curry paste.

    I think the picture isn’t realistic unless you used less broth in this picture. Mine was submerged and unless you took a ladle to bring up forward to take picture, that is how you would see all the contents in dish. This looks like a one skillet dish. Just my opinion.I actually showed a picture by following recipe on the meal plan of what it looks like.
