The smoked paprika is the most important thing in this recipe. If you don't have any, buy a tin of pimentón. You won't regret it. We've made this three times & it's a perfect recipe. Don't worry about having tomatoes, they aren't in season most places. If you insist, plum tomatoes will work. Or add more green beans. Slight variations that are nice: add cilantro (or basil or both) to the parsley. Make this even if you (or your family) don't like sweet potatoes that much; the pimentón cuts the gag factor (we have found:)
