I just got on my computer to look for Pizza Burgers on Dogpile and this is one of the places that came up. I went to school in Mondamin, Iowa. I graduated in 1964. They served pizza burgers at the school. My mom was head cook. They came from Harker Meats in northern Iowa. We would buy them by the case from them. My husband has been asking about them,so was trying to find out if I could still get them from Harkers, but they sold to Reinhart. They were breaded and the sauce and cheese were on the inside of that. We just baked them and boy were they good. Makes my mouth water still and I have been a vegetarian for 17 years. If I ever find them I will let you know. Please post if you ever locate them. Happy hunting!!!
