Swiss Chard Tart is a delicious and nutritious dish that can be made with the help of a food processor. The food processor can be used to quickly make the tart dough by combining flour, butter, and salt. The dough is then rolled out and pressed into a tart pan. The Swiss chard filling is made by sautéing the chard with onions and garlic, then mixing it with eggs, cheese, and cream. The filling is poured into the tart shell and baked until golden and set.
