When I moved out on my own, I asked for the family Kreplach recipe. My Mom ended up giving me her taped up 1954 Settlement Cookbook with handwritten notes in the margins, so I'm guessing a bit on this recipe. My grandmother would save the roast beef & brisket scraps in the freezer until she had enough, and then would make a batch of Kreplach and serve it as a side dish with dinner. It would also make a great appetizer. Imagine a meat ravioli with a slightly crispy noodle dough without any sauce. Many people also serve them in hot chicken soup (in this case it is a bit like a beef Chinese potsticker). I am totally guessing on yield and time since I have never actually made this myself, but will edit the recipe based on reviewer comments or when I make it myself.
