Text: Collard greens are a staple vegetable in Southern U.S. cuisine. They are often prepared with other similar green leaf vegetables, such as kale, turnip greens, spinach, and mustard greens in the dish called ''mixed greens''. Typical seasonings when cooking collards are smoked and salted meats (ham hocks, smoked turkey drumsticks, smoked turkey necks, pork neckbones, fatback or other fatty meat), diced onions, vinegar, salt, and black pepper, white pepper, or crushed red pepper, and some cooks add a small amount of sugar. Traditionally, collards are eaten on New Year's Day, along with black-eyed peas or field peas and cornbread, to ensure wealth in the coming year. Cornbread is used to soak up the ''pot liquor'', a nutrient-rich collard broth. Collard greens may also be thinly sliced and fermented to make a collard sauerkraut that is often cooked with flat dumplings.

Text: Canola oil, or canola for short, is a vegetable oil derived from a variety of rapeseed that is low in erucic acid, as opposed to colza oil. There are both edible and industrial forms produced from the seed of any of several cultivars of the plant family Brassicaceae, namely cultivars of Brassica napus L., Brassica rapa subsp. oleifera, syn. B. campestris L. or Brassica juncea, which are also referred to as ''canola''. According to the Canola Council of Canada, an industry association, the official definition of canola is ''Seeds of the genus Brassica (Brassica napus, Brassica rapa or Brassica juncea) from which the oil shall contain less than 2% erucic acid in its fatty acid profile and the solid component shall contain less than 30 micromoles of any one or any mixture of 3-butenyl glucosinolate, 4-pentenyl glucosinolate, 2-hydroxy-3 butenyl glucosinolate, and 2-hydroxy- 4-pentenyl glucosinolate per gram of air-dry, oil-free solid.''
