Bell peppers or sweet peppers are available in a variety of colors, including green, red, yellow, purple, and orange, as well as sizes ranging from small to softball-sized.
Bell peppers of various colors are the same plant, according to science. The length of time they spend on the vine determines their color, with green being the most common, followed by red or another color.
Peppers are also available frozen, roasted in cans or jars, and dried and ground (as in paprika).
They are low in calories and high in vitamin C and other antioxidants, making them an ideal supplement to a healthy diet.
