Make an Appetizing Soup with a Whole Onion!
The onion is a key ingredient to get this yummy soup right! One whole onion makes a dazzling impression when served. They're also bursting with health benefits. Onions are loaded with nutrients that aren't often found in other vegetables. Good examples are allyl sulfide and quercetin.

Allyl sulfide is what makes your eyes water when you chop an onion, but it also is an excellent nutrient that’s good for healthy blood. Quercetin is a type of polyphenol found in the skin of onions. It acts as an antioxidant that is linked to getting rid of undesired substances in your body.

Take your time to warm the soup, so the ingredients blend well. You will find that the sweetness and umami of the onions creates a tantalizing flavor. In addition, it includes the umami of tomato and tuna. It’s an easy-to-follow recipe that anyone can make. It calls for adding cheese and edamame at the end, highlighting the taste.

You can put all the ingredients in one pot, meaning you’ll have fewer dishes to wash♪
