@greylady: I’d stay away from the oatmeal and the rice for a few days, too. That’s just about the size to get stuck. It’s been a while since they cut the last one out of my mouth, but I still cringe over a painful piece of rice.
To answer the question, what worked for me was some of the other things folks have mentioned including greylady. Soups are good if there aren’t chunks. Also, spaghettiOs, the original kind without meatballs. You don’t really have to chew them and if a piece starts to go somewhere you don’t want it to it’ll just kind of melt away instead of getting stuck. I had a lot of pudding. I wish I’d thought of mashed potatoes. My mouth was sore for a while and I was getting sick of everything I could manage to eat.
