Favorite: 
Anything with cheese, probably (mac & cheese, pizza, cheeseburgers, etc)
Fruits (apples, grapes, cantaloupe, pineapple etc.)
I also like rice dishes (pilaf, chicken & rice)
Seafood, especially haddock, cod, or shrimp
Least favorite: 
Spicy food, undercooked or raw food (like medium rare burgers or sushi), foods with a mushy texture (like oatmeal)
I'm not exceptionally picky. It seems like my preferences have more to do with the way the food is prepared.
