I would not eat oatmeal every day, but steak, eggs or bacon.. sure.  Oatmeal might be advertised as a health food, but it is missing essential proteins and essential fats, but steak (non-trimmed) would have quite a few essential proteins and essential fats (eggs and bacon too).  You have been propagandized if you believe that oats and/or grains are healthy as compared with meat, and sure probably the most unhealthy part of the pizza is the bread (the dough), even thou some guys have been substituting with other ingredients, and frequently few fatty meats on their pizzas. which fatty meats are healthy, contrary to popular propaganda that might be wanting to vilify fats. 

Thin crust pizza is probably healthier than thick crust, and sure I admit that the bread will taste good, and it could be a bit of a challenge to have both a healthy crust and to have it taste good.. . and noodles and corn for a pizza is quite weird, even though I still sent participation merits to some of those seemingly crazy pizza concoctions.  I understand if people don't have an oven (or even one of those small toaster ovens), then perhaps putting in a frying pan could be a substitute, even though it seems to take something away from the baking part of the pizza (the convectional air circulation that cooks the top of the pizza)... and sure, I am not sure how the Italians feel about the fire-pit oven pizzas... sometimes harder to control the heat level with some kinds of cooking.
