I think my favourite Lidl thing is the Full fat Greek yoghurt. It's the tastiest one around.
For lunches the falafels and seeded flat breads with salad and Tzatziki (if it's Greek week - otherwise make your own with the Greek yoghurt)
Bagels, cream cheese, cucumber
The antipasti is usually pretty good - spicy peppers stuffed with feta, herby olives. Their various nuts are good snacks too - the spicy tomato mixed nuts and the salt and pepper roasted cashews are popular.
For kids snacks and lunchboxes the chocolate coated rice cakes, dried mango strips and forest fruits crispy slices are good. There are sone lentil based salt & vinegar crisps in a multipack (black & blue packaging) which my children are always excited to get in a packed lunch too.
Generally I don't find the fruit and veg lasts very well so I only buy stuff that is likely to get used quickly and top up somewhere else later in the week. I do like the bags of mini seedless peppers though. Tasty, crunchy and keep well.
I don't eat meat but everyone else has enjoyed chilli & bolognese from the organic mince. Also the Aberdeen burgers are popular (served in sesame seed brioche buns). I've also given the family bbq pork ribs with rice & peas quite a few times. They also seem to enjoy the tempura chicken pieces.
