Green chili, also spelled as "green chilli," is a variety of chili pepper that is harvested when it is still green. It is commonly used in cooking to add heat and flavor to dishes. Green chilies can vary in spiciness depending on the variety, with some being mild and others very hot. They are often used in Indian, Mexican, and Thai cuisines, among others, and can be added to curries, salsas, stir-fries, and other dishes to add a spicy kick.
