What?
“Eh? ‘Uncooked’? Oh, dear…I see you’ve never had Peppers Tartare.”
There. Sorted. 
dwest could confirm this recipe for me, it’s Slovak. My Mom, mixed uncooked ground beef, rice, onions, & spices. Stuffed that mixture into green peppers. Put those stuffed peppers in a roasting pan, poured in tomato juice that she canned to top if off, maybe added some tomato soup, and let that simmer for hours until dinnertime.
This is a familiar dish to me, too. I’ve never made them myself - I’m not a fan - but I would say that the “for hours” part is key. I’m guessing an hour and a half minimum in a 350 degree oven, give or take.
“simmer for hours”? Now I know what I did wrong by broiling for 20 minutes…but don’t worry, I don’t cook for anyone else anymore, so yer all safe! 
There was that time I was gifted some rhubarb so decided to make pie… never made it myself before and my mum couldn’t find her recipe, so I googled it.
“That’s an awful lot of sugar,” my mom commented as I dumped it in. “It’s what the recipe said,” I told her.
Um. Yeah. It was an awful lot of sugar. Like, crunching on lumps and I bet the dentists of all of us who were eating it were planning their next vacations. (Yes, I fed it to friends, because they happened to be over that night. Poor things. And yes, I made two because I had lots of rhubarb. Poor me.)
And that is how I learned that it is okay to get recipes off the 'net, but you should probably read several and make sure they tend to agree as a general rule…
