Lettuce is an annual plant of the daisy family, Asteraceae. It is most often grown as a leaf vegetable, but sometimes for its stem and seeds. Lettuce is most often used for salads, although it is also seen in other kinds of food, such as soups, sandwiches and wraps; it can also be grilled.

The bell pepper is the fruit of plants in the Grossum cultivar group of the species Capsicum annuum. Cultivars of the plant produce fruits in different colours, including red, yellow, orange, green, white, and purple. Bell peppers are sometimes grouped with less pungent pepper varieties as “sweet peppers”.

A cherry is the fruit of many plants of the genus Prunus, and is a fleshy drupe. Commercial cherries are obtained from cultivars of several species, such as the sweet Prunus avium and the sour Prunus cerasus.

Okra or Okro, Abelmoschus esculentus, known in many English-speaking countries as ladies’ fingers or ochro, is a flowering plant in the mallow family. It is valued for its edible green seed pods. The geographical origin of okra is disputed, with supporters of West African, Ethiopian, and South Asian origins.

Romaine or cos lettuce is a variety of lettuce that grows in a tall head of sturdy dark green leaves with firm ribs down their centers. Unlike most lettuces, it is tolerant of heat. In North America, romaine is sold as whole heads or as “hearts” that have had the outer leaves removed and are often packaged together.
