Pizza rolls are a very popular street food and this tear-and-share traybake makes a great and always welcome addition to an informal dinner buffet, a picnic or a kids’ birthday party.
Common fillings include the usual tomato sauce, mozzarella and often ham; however, this recipe uses one of my favourite combinations based on ripe red sweet peppers and onions. The vegetables are simmered before being blended to a cream: the cooking brings out their sweetness and makes them easier to digest. The creamed filling also makes a delicious dipping sauce, so don’t throw away any leftovers!
Here is a technique you don't hear much about. The idea is to cook peppers and onions in a hot dry pan, relying on the moisture in the vegetables to keep them from burning (though they do char in a pleasant way). Since both the vegetables are high in water content, they begin to steam, but the high heat evaporates the steam immediately. As they are stirred, they start to take on a bit of color and soften. Once they are half-cooked, add salt and a small amount of oil, which allows them to caramelize, intensifying their natural sweetness. Eat them hot or cold. They're good plain, but I usually add garlic, hot pepper, parsley or basil, and a little vinegar too.
