Welcome to the forum RoastedRedPeppers~you've found a great forum!
Since your surgery was only two weeks ago, things are still stinky, but hand in there it will get better! In the mean time, you could try M9 Drops...I've found that they can cancel out just about
any smell
(You can order them from your supply company)
Other things to try are Peroxide and Mouth Wash. I've tried most of them and don't really bother with concealing the smell in the ostomy pouch but do spray a deodorizing spray into the toilet BEFORE I empty to help with the smell if I've eaten a smelly food.
Once you get back to eating more diverse foods you'll find the awful smell will subside
