Cha lua or gio lua (Vietnamese ham/sausage) is another common item on the traditional Tet menu. As we mention, Tet is a time for families to come together and celebrate the new year with a fresh start. But it's also a time to remember and honor the past. During Tet, cha lua is frequently used as an offering to relatives that have passed and placed before the ancestral alter in each home. And of course since it's a filling for the traditional new year snack banh day (sticky rice cakes), you can't have a shortage of cha lua around the house during Tet.
