I have several relatives who eat Chorizo (spelled Chourico in Portuguese) as a diet staple and are quite healthy. Like any sausage, it contains some degree of fat. Linguica, a related Portuguese sausage, but not quite as spicy, is made from the same ingredients. You may want to contact a manufacturer for specific nutritional information. Living in the mid-east, I am not able to buy quality Chorizo or Chourico locally. The versions I can find are greasy, oily, and don’t taste like they are good for you. Quality Chourico and Linguica is great for sandwiches, omelets, and in spaghetti sauce. My favorite brand is Gaspers, from New Bedford, Massachusetts. They make a very lean sausage (not greasy) and even offer a turkey-based product, and they sell on-line! Here’s their website: http://www.gasparssausage.com/ourproducts.html
If you like Portuguese foods, Gasper's also sells Sweet Bread. If you are unfamiliar, sweet bread is similar to Hawaiian bread, since it was brought to the islands by Portuguese sailors in the 1700’s. It is slightly heavier and sweeter than Hawaiian bread.
