Bacon Bits in a bowl (Public Domain)

Bacon bits are small pieces of crumbled bacon used as a topping in salads and also as part of many recipes.

Commercially produced bacon bits are sold pre-cooked (usually in industrial-grade continuous microwave ovens), made from the tips, ends, and uneven parts unsuitable for commercial-grade sliced bacon, smoked, salted, and packaged in air-tight bags or glass containers.

Other types of products are packaged and sold as "bacon bits", ranging from pork/ham by-products smoked and salted to have flavour similar to real bacon, to turkey bacon bits and soy-based protein "vegetarian bacon bits", which are wholly unsuitable for use in many recipes actually calling for bacon bits.
