Vietnam is famous with its traditional and delicious dishes. All of them easioly bring to anyone's mouth indeed, but as myself, I enjoy spring rolls best. Spring rolls are lightly fried rice -paper rolls, smaller and crispier than Chinese egg rolls but more flavorful. They are filled with highly seasons morsels of crab, shrimp, chopped vegetables, onion, mushroom, vermicelli and eggs. To prepare them, place the above mentioned filling on a thin rice pancake, roll up then fry. Finally, spring rolls, when fully prepared, are wrapped into some kinds of fresh vegetables, then doused in fish sauce. My mother usually cooks spring rolls for me, especially on important days in year, such as Tet holiday. When I eat them, I feel all of my mother's love that she reserves for me. To me, they're like the most special dish in this world
