Hi A.,
I may not be much of a help, but wanted to commiserate with you a bit. I had my gall bladder taken out the same day you did! Mine was infectious and had 24 stones. The incisions are healing, but most of the pain is from the excess skin glue peeling off. That stuff hurts!
Since the surgery, I've been able to eat pretty much anything. I took it easy during the holiday, but after that started to "test" out how things were working. The only problem I had was when we went out to eat at Chevy's. I felt ill after, no excrutiating pain but some cramping. Can't say if the Mexican food was to blame or not because I had had home-cooked Mexican food before then with no problems. Even pizza, which used to give me awful pains before the surgery, didn't give me any problems.
My sister had the same surgery done 8 years ago and, since then, she simply eats healthy. She may indulge occasionally, but nothing seems to bother her.
Hope that helped a bit and good luck on your recovery!
