Fruit and veg is pretty good, as long as you’re eating it fairly quickly.
Am always really impressed with their meat - steaks are reasonably priced, free range chicken if they have any left is better value than other supermarkets, pork & apple sausages are excellent. The salt and chilli pork belly slices are INCREDIBLY spicy. Their fish is good and well priced.
Baked beans, their version of Nando’s marinades, soup in a cup (DH says theirs are better than the branded ones), olive oil, tinned tuna, microwave rice, their specially selected jars of curry sauce with the dried spices are v tasty and so easy if you don’t want to cook from scratch, their versions of Snickers, Mars, and Twix.
Fruit juices, kids smoothies, yoghurts, butter, most of the cheeses.
Pretty much all of the breaded fish / chicken products from the freezer, and their Magnum dupes are excellent.
