Yes, pepperoni can be considered a good source of protein. A one-ounce serving of pepperoni typically contains about 6 grams of protein, which is about 12% of the daily recommended intake for the average women (50 grams) and 10% for the average man (56 grams). However, keep in mind that pepperoni is also high in saturated fat and sodium, so it should be consumed in moderation as part of a balanced diet.
