Try to keep sopes, beans and chorizo warm at the time of assembly, but if any of them got cold during the process, just spread the beans and spoon the chorizo on top of each sope and warm up the assembled sope on the hot griddle or skillet for a minute or two, being very careful not to burn the sope bottom. Thay can burn very fast if you don't watch it. Remove carefully with a spatula and then garnish.
