Romeritos

Romeritos is a Mexican dish from Central Mexico,[1] consisting of tender sprigs of seepweed (Suaeda spp.)

that are boiled or steamed and sometimes served in a mole poblano flavored with dried shrimp.

Typical additional ingredients include boiled potatoes, nopales, and shrimp -- sometimes fritters of dried shrimp[2] with bread slices and in tacos.

They are traditionally enjoyed at Christmas and Lent.

That name in English means "little rosemary"; some seepweed species can vaguely resemble such a plant when fresh, but neither the taste nor the fragrance is similar in any way.
