cabbage soup with broccoli

Do i have to stick to the exact soup recepies, or can i add vegetables for variation?
And am i allowed to leave out ingredience in the soup, for example if i cook it without peppers but with broccoli instead?

Of course you may vary the soup according to your taste. Find here even more cabbage soup diet recipe variations.

To use broccoli instead of peppers should be ok - potatoes for example are NOT ok.

All the best.
