Hollow it out and put your meatloaf Mix inside it :)
just make the mix more Dry than usual.
I cut mine in half, scoop out the seeds score the inside with a knife but no too deep, rub with a little salt and leave it stand for an hour.
drain them (liquid will form in the bowls).
then pack with pre-cooked Lamb or beef mince and soaked (but not boiled) Rice, along with chili peppers, onion fenugreek leaves salt/pepper to taste and any other spices you like (it`s Very flexible recipe), then when the bowls are full top with some cheese and then wrap them in 2 layers of tin foil and bake in the oven for a good hour and a half on about 200c
put the whole thing foil and all into a Bowl each, then Very carefully open the foil, you WILL get steam burns if not carefull!
serve with some crusty bread :)
So long and Thanks for all the Fish ;)
