Lidl do some good stuff, spicy peppers stuffed with cream cheese, all different hams etc.
Make some little bruschettas, top with cream cheese and smoked salmon, and chopped tomatoes and basil. I found some ready made bruschetta in M&S, and their smoked salmon was on offer too. It was absolutely delish.
Or put slivers of salmon out so your guests can assemble their own.
Sometimes I put some soft cheese on an anti-pasti plate. Something like a camembert which is creamy and oozes is lovely with the spicy stuff.
Olives, chargrilled peppers, onions in balsamic vinegar (and use the vinegar for dipping bread in too).
Don't go too mad on bread, go for crackers or thin toasts, it will be too bulky and filling.
