Peppers have a sweet, mild flavor and are available in green, red, yellow and dark yellow. Peppers color up as they ripen on the vine and follow the mature green stage. The brighter colored peppers tend to be sweeter than green peppers because the sugar content increases as the pepper matures.
Peppers are high in vitamin C and excellent sources of dietary fiber and provide small amounts of several other vitamins and minerals. Sweet peppers have thick flesh, are crunchy and juicy, and often eaten raw, sautéed, roasted or stuffed.
Here’s a tip: Look at the bottom of the pepper and count the lobes. If it has four lobes it’s a female pepper, which produces more seeds and is sweeter than a male pepper, making it a good choice for crudités or chopping into salads. Male bell peppers have three lobes and are a good choice for roasting and making stuffed peppers

The terms bell pepper (US, Canada, Philippines), pepper or sweet pepper (UK, Ireland), and capsicum (Australia, India, Malaysia, New Zealand, Pakistan and Sri Lanka) are often used for any of the large bell-shaped peppers, regardless of their color. The fruit is simply referred to as a “pepper”, or additionally by color (“green pepper” or red, yellow, orange, purple, brown, black).^[6] In the Midland region of the U.S., bell peppers when stuffed and pickled are sometimes called mangoes.
