With their bright colour, which is often yellow, red, green or even orange, peppers are ideal for the preparation of a large number of dishes, starting from salads, passing through first courses with pasta, without forgetting the second courses with meat and fish. Peppers are very low in calories and, on the other hand, they are real concentrates of vitamins, even to a greater extent than many citrus fruits, although this peculiarity is not often made known.
