sunflower seeds?! Now I have to go back. I used to go to LIDL all the the time since it is the only grocery store in easy carrying distance before I got the car. I still go sometimes, not for my regular shopping trip, but for items I'm craving.
You've covered all my favorites (the chocolate prices can't be beat!!), but one hasn't been mentioned. There's a muesli there that I just crave. It comes in a small bag with blue on it. I really don't like most of their cereals, but I haven't found a muesli like this. It isn't all oats like so many of the others. It is chock full of whole almonds, banana chips, dried fruit, pumpkin seeds, lots of great stuff. It really is mostly fruit and nuts and oh so yummy!
You definitely learn to pick and choose at that store, but what is good is oh so good and the rest you can leave at the door.
