Stuff some stoned dates with blue cheese, wrap in bacon strips. Freeze. No problem - straight from the freezer to the oven.
Try some empanadas - little pastry discs stuffed with a little minced meat, or curried vegetables, or a spicy tuna mix, then folded in half and sealed with a fork. Freeze. Oven straight off. I serve these with chutney.
Peperonata/aubergine antipasto etc., will keep for 3 or 4 days in the fridge with no trouble at all.
Tapenade and all its mutant forms (!) Classic tapenade is olives, capers, garlic and olive oil, all chopped up and spiced with black pepper. If you care to stick it in a bottle or jar, and leave it in the fridge, it'll last for ages.
(The mutant forms are the "new" tapenades, you know - artichoke and sundried tomato tapenade ( NOT! a tapenade); Mediterranean parsley and red pepper tapenade....
A dear friend's special idea... take a piece of sandwich bread and press it into a muffin tin mould or tartlet mould. Fill the "bread) mould with creamed artichoke, or creamed leek and bacon. Freeze. Remove from tins and put into plastic bags in the freezer.
