Yes. Modern Polish cuisine can be very eclectic, and there's also modern takes on traditional recipes.
A lot of things grow well in PL, however the centralised distribution of foods from 1948 to 1989 (and if truth be told, afterwards too) as well as the very lean years of the war, had an effect on what made it to the shops.
Oops I forgot to ask if eggplant is popular in Poland
It was rare until a few years ago, now it's easy to buy. Courgettes are very popular, as are red/green/yellow peppers. Traditional tastes tend towartds the bland, however chillies etc are becoming more popular.
There were some rather 'posh' recipes like poppy seed pierogi and pierogi Lwowskie (filled with something like a dryer bolognese sauce) which became rarer but are now making revivals. The economic decline of the better off and more cosmopolitan people (who suffered terribly in the war and shortly afterwards) meant that traditional Polish food and 'peasant food' became almost synonymous, and some things fell out of fashion.
Income levels are unfortunately still low, and this does have a bearing on what people eat. As you'd expect, people in cities as well as people who've travelled, are more adventurous.
Right now, if you go to potluck meals etc in Warsaw, tabbouleh seems to be everywhere.
Some older traditional foods are making a comeback. Czeremcha, used in winemaking is something that is modestly regaining popularity.
