Even before I was married, I heard about this recipe. I worked as a temp at a local soda packaging plant, and on lunch break, I smelled the most divine leftovers and covertly eavesdropped on the conversation about how they were made. Unfortunately, I was too shy to ask for the actual recipe, but, years later, after I had moved on to a permanent job elsewhere, that same person came to work at my new job and I asked her about it then (crazy stalker lady that I am). I took it out recently, dusted it off, and now we've decided it's going to be a fallback for when we need an easy meal!
Mix ground beef and egg together. Add rice, onion, spice mix, salt, and pepper slowly and work together with fingers. Form into golf balls and place in skillet. Add tomatoes and cover. Simmer over low heat for about an hour, turning balls over at least once.
