That looks delicious, I have used onion but never thought of adding the lemon like that.

Lemon peel grated with herbs I place under the skin on the breast, salt and spices on the outside, one onion inside as stuffing or a bread crumb stuffing @braaiboy

A recipe I found interesting here in Steemit, pork mince used as the stuffing, never tried that, could make for an interesting variation.
