I am taking a guess here I haven't made them individual for quite a while, since we are retired folks. I usually just make it as a pasty pie in my square Corning ware fry pan and bake in oven.
I am guessing my original recipe will make about 4 pasties. Once you make them you can judge the amount of veggies to use.
There is another recipe listed here with the pie crust and that is the same as mine. But since I am retired and don't have to make my own crust. I use the refrigerator ones, just being lazy I guess or more time for sewing!!
