Beans are a great source of plant protein, providing all the amino acids except the sulfur-containing amino acids. Adding the toasted pita chips complements it well, making this mediterranean bean salad a complete meal that is satisfying and filling. These beans also provide dietary fiber and have a low glycemic index. And the salad as a whole, is packed with vitamin C, potassium, monounsaturated fat and some B vitamins. The herbs and spices further enhance the phytochemical and antioxidant content of the salad.
