Ok this is not an exact recipe, more of a throw in what you have but basically;
1 1/4 lb mince
1 onion chopped
salt & pepper
would be good as is but
Now down to your own imagnation!
herbs (what ever you have)
experiment! You won't go far wrong.
Have done it with all of the above but you don't really miss one when it's not there. Have done just the basic mix and been blessed with compliments !
just make sure well seasoned, fairly hot oven 20 mins, slice of cheese, optional fried onions. Done!
More to come!
