I had maybe 3/4 pound pot roast left over from when I made it Sunday and maybe 1/2 pound left over from when my Mother in Law made it on Tuesday (we often end up making the same things). We really didn't want any more pot roast. So I googled for ideas and came up with empanadas.
The dough was this one: https://www.laylita.com/recipes/how-to-make-empanada-dough/ . Her instructions were very clear and very helpful.
The filling was based on this: http://www.foodnetwork.com/recipes/empanadas-recipe2-2041608 but with changes based on what I had.
Shred/chop pot roast, set aside
saute 1 onion (chopped), 3 cloves garlic (minced), 2T tomato paste, 2t cumin, 2t chili powder, shake of cayenne, 1t oregano, salt, black pepper, red bell pepper chopped
(I did mean to put in the vinegar but I guess I forgot).
Turned out beautifully, but baked a lot longer than expected and still didn't get as dark as hers.
