Irish/Mexican Social Event. The Argonne Hispanic-Latino Club hosted a social event on Thursday, March 22, from 11:30 a.m. til 12:30 p.m. in Bldg. 205. Lamb tacos with lettuce, tomatoes, sour cream, cheese and salsa were served. Green vanilla floats were also available. In Mexico, lamb is cooked underground to make a dish called "barbacoa." Lamb is also one of the main foods in Ireland, made as a stew dish. Manoel Conde made an interesting presentation on Brazil.
