Cowpea crop is known as "Vegetable Meat".
Cowpea (Vigna unguiculata) is a legume consumed as a high‐quality plant protein source in many parts of the world. High protein and carbohydrate contents with relatively low-fat content and complementary amino acid pattern to that of cereal grains make cowpea an important nutritional food in the human diet.
The cowpea has often been referred to as "poor man's meat" due to the high levels of protein found in the seeds and leaves.
