I'd do those instead of the olives. Or red peppers. Or something colorful.
I've just never been all that nuts about olives, too many are salty.
One caveat, the "good quality olive oil." Don't fall for the fancy bottles, it's all the same unless you know an old farmer in Spain, Italy, or North Africa who grows his own olives and uses an old wooden press and produces the high flavored, rather dark green stuff. Otherwise, it's McOlive, all roller pressed in huge batches and sold to various labels. I've never had bad oil from either Bertolli or Colavita. The bottles aren't much fun, but the olive oil is predictably decent. Just don't buy that clear, colorless stuff, it's extracted from the pressed olive mash by chemical means and has no flavor at all.
When you buy olive oil in fancy bottles, it's the same stuff, you're paying extra for the fancy bottle.
Italy is the biggest exporter of bottled oil. It's the biggest importer of mass produced, pressed olive oil.
There was a huge scandal some years ago when it was found that olive oil (mainly sold in Europe) was actually soybean oil with coloring and some flavorings added. The industry has cleaned up its act since then and testing in the US shows it's all the genuine article. Just be aware that pressed oil from various countries is mixed together to make the final product.
Tl, Dr: Olive oil is big business. The country on the label doesn't indicate the country whee it was grown or pressed. The labels Extra Virgin and Virgin have lost their meaning, it's all one pressing. Stay the hell away from that yellow stuff with no flavor, it's not good.
