The type of breakfasts i eat in poland a pretty much as described by kasper in the post you linked to... the only hot dish i have had have been eggs... scrambled, fried or boiled...
Quoting Kasper
"Good Polish breakfast is usually chleb (bread), an assortment of szinki (cold meats), eggs are popular too. My family usually has cottage cheese/farm cheese as well.
A really big brekkie may include some cold smoked fish, a cold salad and some other nice things including the best bread money can buy and freshly churned, lightly salted butter."
