Pak Choi is a fast, easy-growing microgreen with a unique mild flavor. Goes well in any micro salad, and can be grown to the baby salad stage. Compared to its other vegetable families like cabbage and cauliflower, pak choi, or bok choy, contains more vitamin A and carotene. To be able to meet the required levels of vitamin A, eat 100 grams of pak choi. Aside from vitamin A, it is also rich in vitamin K, B-complex vitamins, calcium, and iron.
