To make sure your Broccoli Cauliflower Salad is not only packed with flavors but also suitable, for those following a gluten-free diet it's important to pay special attention to a few key ingredients. While fresh vegetables, cheese and sunflower seeds are naturally free, from gluten, bacon and mayonnaise can sometimes pose a challenge. When purchasing bacon opt for a brand that clearly states it is gluten-free as some variants might have additives that contain gluten. Similarly when choosing mayonnaise go for a brand that is certified as gluten-free.
