The amount of broccoli and cauliflower used in this salad is not absolute; after all, I just used up what was in the fridge. Proportion-wise, as you can see from the photos, the broccoli is much more prominent. You can trim the broccoli stems and save them for soup. Or, go ahead and just dice them and add to the salad. If you increase the amount of veggies in the salad, you may need to add more lemon juice, oil, and seasonings — just keep tasting until you get it right!
