Long pasta is still my worst. I have a near-choking or clearly gagging episode every single time. I don't eat a lot of meat, so even if I get penne, it's probably coated in cheese which also wraps around the brackets and just clogs everything up!
Broccoli, asparagus, lettuce, beans any green veggie with little sprouts or bits tend to be a "blast" when I go after them with my waterpick! They're hidden everywhere.
Salsa, chili, granola, breads and rice have all had their own little interesting stories for me.
I've found there's not many foods I CAN'T eat, I've just started changing the way I eat them so at the very least, you can't see it all hanging in the front (usually). Then again, I was at a business meeting last week in the boardroom and did not realize we were having lunch. I was eating a sandwich with lettuce and whatnot, there was a drink and pickles to help wash down the "muck" but the one guy had to keep trying to speak to me the moment I put a bit of the sandwich in my mouth. So not only do I have food in my mouth, but it takes longer to chew and clear it out before I dare to open my mouth knowing I may show mucky teeth lol!
