Derived from its 'bell' shape, "sili" is a type of large mild chili pepper that is considered by many to be without heat. It is mostly considered a vegetable rather than a spice because of its mild chili taste, though some people also find it slightly hot. Bell peppers are green while developing and then ripen to a variety of colours, of which red and yellow are the most common but purple and orange are also found.
Placing bell peppers in a preheated broiler or griller can add a distinctive smokey flavor. Bell peppers are commonly added to pizza, stir-fry, and sweet and sour. They can also be opened at the top and deseeded, then stuffed and baked. To prepare bell peppers, slice it horizontally in half, deseed it and slice it to preferred size.
