Uncut cherry tomatoes in a tortilla wrap. It's actually what I'm eating right now (well, not just tomatoes; it's also got chicken and chopped-up celery.)
Why don't you guys use sauces made using tomatoes? I've always hated tomatoes in my sandwich. Forget them falling out... Biting into them is disgusting as well!
Are you kidding me? The texture is the worst part. The taste of raw tomatoes is the second worst. They only start to get good after you cook the living hell out of them.
I find it interesting that you call them acidic. I've never had a tomato which tasted acidic to me, except maybe if they aren't ripe yet.
In fact, it's quite common to add vinegar to tomatoes (ketchup, tomato salad, various dishes with balsamic vinegar). So, yeah, maybe your sense of taste picks up on some molecule that others can't taste...
My cousin always used to eat his thanksgiving turkey with ketchup, despite my mom making the best goddamn gravy in the known universe and slightly beyond.
