This dish is years old. I believe my mom discovered it in a Kraft Grated Cheese (a ka sawdust) advertisement in a publication, as that is what the dish initially required. (Do not stress; I changed the Kraft with Parmigiano-Reggiano as quickly as I vacated on my own).
I believe the problem is the tomato paste; it does such an excellent task of softening the hamburger the patties are really tough to prepare. They break down. I normally prepare them in my (well-seasoned) cast iron frying pan however attempting to turn them is rather the obstacle and hardly ever effective. A minimum of not in one piece, that is.
When the patties are done I need to attempt to reassemble the pieces on the bun. Puzzle Hamburger!
( FTR, my mother utilized to have the very same issue when she made them. You may believe the Kraft [sawdust] would have bound those patties together however noooooo).
Any tips for modifications that will not impact the taste?
1 1/2 pounds. hamburger
1/2 c. newly grated Parmigiano-Reggiano

1/4 c. carefully sliced black olives
1/2 tsp. outright
