פירוש על עבודה זרה 117:9

According to R. Yohanan the lupines cooked by Gentiles are prohibited only because the people of Gavla are not “students of Torah.” The implication is that they are lax in their observance and in consequence, the halakhah must be extra stringent with them. But, as we shall see, lupines should have been prohibited in any case.

Lupines cannot be eaten raw. Therefore, the prohibition of food cooked by Gentiles should, according to a statement made by Rav, apply to them. This was an issue more fully discussed way back on 38a.
