I am sure you have heard the saying “eat the rainbow.” While there is a lot of truth to the fact that more colorful foods have very important nutrients, there are plenty of benefits to eating white and neutral-colored vegetables, like mushrooms, onions, garlic, and, our favorite, cauliflower. This plant-based cauliflower soup has 4 powerful white-colored vegetables – cauliflower, onions, garlic, and a crispy mushroom topping.

Neutral-Colored Vegetables Are Healthy Too

Cauliflower

Cauliflower is the main star in this creamy cauliflower soup. This veggie has had its moment of fame in the past couple of years. Cauliflower is a high fiber vegetable that is also high in vitamins like vitamin C and folate. It is also full of antioxidants and phytochemicals which help fight against cancer. It is also a very versatile vegetable! You can eat it raw, roasted, in “rice” form, pickled, pureed, in a soup, or in a sauce.

Garlic

Garlic is famous for its antioxidant properties and its immune-boosting abilities, just to name a few of its many benefits. It is also one of the most used aromatics in cooking, and it adds so much flavor to food! 

Onions

I am a firm believer that every recipe should start with onions and garlic. As Chef Julia Child once said, “I cannot imagine a world without onions.” She was absolutely right! Onions add great flavor and fragrance to any dish. In addition, onions have antioxidant properties that help protect against cardiovascular diseases and cancer. 

Mushrooms

Although the crispy mushrooms in this recipe are optional, mushrooms are another neutral-colored food with many, many benefits. A nutrient powerhouse;  mushrooms are high in fiber, vitamins (potassium, B-vitamins) and antioxidants. AND, did you know, they’re the only source of vitamin D in the produce aisle? To be fair, they often don’t get the credit they deserve. Check out one of our favorite recipes that features mushrooms!
