Yes, Aldi in the UK does sell gluten-free bread. One example is the BFree pittas.
However, it’s worth noting that the availability of specific gluten-free products may vary from store to store. This variation in availability could be due to factors such as local demand, store size, and logistical considerations. Therefore, if you’re planning a shopping trip to Aldi specifically for gluten-free bread, it may be beneficial to check in with your local store ahead of time.
