In a large saucepan, heat the 1/4 cup of olive oil. Add the crushed garlic and the onion and cook over moderately low heat until softened, about 5 minutes. Drain the <em>farro</em> and chickpeas; add them to the saucepan along with the chile and cover generously with water. Bring to a simmer, cover and cook over low heat, skimming occasionally, until the chickpeas are almost tender, about 1 1/2 hours. Uncover and continue simmering until completely tender, about 20 minutes longer. Remove from the heat.
