Wheat or Oats as mentioned...another good crop/seed to plant would be turnips,or the Rape and Brassicas blend in "Shot Plot",groundhog raddishes are another good plant to put out that will have some nice big green leafs.Most of these just need a light disc-ing and breaking up of the soil to grow.....wheat and oats are about the quickest and easiest of them all.I think Evolved Harvest also makes a "Throw & Grow" blend for quick and easy food plots but breaking up the soil will better Your odds even if all You have is a smal ATV disc would be better than bare grassy ground!
