Wir haben zum Abendessen einige leckere Bohnen gekocht.

English Translation

We cooked some delicious beans for dinner.

I guess 'einige" has the “einige leckere Bohnen” construction. The delicious beans = Die leckeren Bohnen. All plural forms of adjective declensions use the -en ending, except with there’s only one adjective describing the plural noun. That confused me a bit. Einige is NOT an adjective, but either an article or a pronoun.

The frying pan method for German adjective declensions has really helped me “almost master” German adjective declensions, apparently. LOL
