Wonderful meatless dish! This doesn't remind me of pierogies, since there is no potatoes or cheese, but it's great anyway. I had to guess at the sizes of packages, since none are given. I used a 16-oz box of (rotini) noodles and a 16 oz jar of sauerkraut. That seemed to work out well. I added salt, pepper and some caraway seeds. This is a keeper. Thanx for sharing.
