14 days post-op first time throwing up

I was finally having an ok morning... had yogurt and v8 for b'fast... no snacks(not that i didn't want them), and went to lunch with a co-worker. Ordered beans and shredded chicken with pico in a bowl... took a few bites and had to run to the restroom... first time throwing up, I could clearly see (in the bowl) why It happened... I didn't chew well at all.

I'm empty again now and sipping water. I am afraid to eat again. How long should I wait, or should I just do pudding and stuff the rest of the day?
