Just wipe them clean with a damp kitchen towel and cook them as you would :-) Personally I love to cook them on a low heat with creamery butter with crushed garlic and topped with finely chopped parsley and coriander :-) Yum yum..!
Have you heard most of us are low on vitamin D because we don’t get enough sunshine? Plant foods do not naturally contain vitamin D but mushrooms because they are a fungi and grow in the dark have plenty enough. They are good sources of vitamin B and also Selenium. Selenium is a mineral that works as an antioxidant to protect body cells from damage that might lead to heart disease, some cancers and other diseases of aging. Many foods of animal origin and grains are good sources of selenium, but mushrooms are among the richest sources of selenium in the fresh produce aisle. This is good news for vegetarians, whose sources of selenium are limited.
A 100g of fried mushrooms typically contains 157 calories, 16.2g fat, 0.3g carbohydrate, 2.4g protein. Mushrooms are also high in copper.
