I made this the other day for Travis for lunch :) I am too lazy to type it all up so here is a link to the recipe
But here are the changes we made to make it a pizza. We used pizza sauce instead of the mustard, pepperoni in place of the lunch meat, and we just used cheddar/mozzarella cheese. We used a cut up pepperoni for the tongue and black olives for the eyes! It sure was tasty!
