Start by spreading the peppers and potatoes in a pan. Add a little olive oil, salt and pepper and cook for about 25 minutes. Peppers may want less.
Meanwhile, in a bowl, add the onions, fresh and dried, the parsley, the boiled beans, the peppers and the potatoes and the grated cheese (if you choose to add). Add a little olive oil and salt, mix and enjoy.
If you do not have ready-cooked beans you should start by boiling your beans in salted water for as long as it takes until they soften.
