Substitue for Semolina

Semolina is coarsely ground durham wheat flour, cornmeal would be similar in texture but would offer a different flavor, that said I think that in the quinoa cakes it would be tasty, if you happen to have cream of wheat cereal you could use that also. I looked at the recipe and since it's cooked, polenta or cornmeal would IMHO would be fine to sub.
