One and two don't sound gross. Banana and peanut butter sandwiches are too rich for me, though. I imagine maple syrup would make it so I wouldn't even be able to chew.
I'm someone who loves garlic. Lots of garlic. Cooked into everything, on my pasta, roasted and rubbed onto toast, chopped up raw and put on pizza(Seriously, try this. It's awesome). But everyone I know seems to be put off by the amount of garlic I enjoy, compared to them. I used to eat 2 or 3 cloves a day, more if I was making a garlic-dish or if I roasted it. I don't anymore because I really don't have that much money.
I like to dip my french fries in gravy, which makes perfect sense to me, but no one else in my family.
Not really gross, more extreme, I always keep a bottle of sriracha nearby to spice up anything that doesn't have enough flavor, usually rendering my food unsharable because of heat.
I like to dip bread into things, but my best friend will actually get physically sick if I do that around her. XD
