Broccoli Substitution: Cauliflower florets can be substituted in for broccoli florets at a 1:1 ratio. Alternatively, you can use both cauliflower florets (½ lb) and broccoli florets (½ lb) for a Broccoli Cauliflower Salad.
Monk Fruit Sweetener Substitution: In place of monk fruit sweetener, erythritol or Swerve can be used at a 1:1 ratio. To substitute stevia in, I would suggest using pure powdered stevia and, since a little bit goes a very long way, start with only ¼ tsp and then taste test before adding more.
Sunflower Seed Substitution: If you do not have a nut allergy or intolerance, slivered almonds or chopped walnuts can be substituted in for sunflower seeds at a 1:1 ratio.
Storage: Store broccoli salad in an airtight container in the refrigerator and consume within 2-3 days.
