Fennel and grapefruit make a classic, delicious, and nutritious combination.It also happens to be one of our favorites. This salad boasts many detoxifying properties. Fennel and thyme are both rich in volatile oil compounds that have antimicrobial and antibacterial properties. Thyme also protects and increases the absorption of healthy fats. Aside from its health benefits, this salad tastes like the Mediterranean. We eat it all winter.
