From the thread on garlic/onion powder, I realized there were a number of standard American dishes that I just don't make. Not that I don't like them, but they just don't beat out other ones. Here's my short list, what's yours?
Creamy dips for chips (I do guacamole/salsa)
Meat loaf (I do meatballs)
Baked potatoes (I do roasted/mashed)
Baked beans (I buy a can once a year)
