Add all the ingredients for the lemon poppy seed dressing except for the poppy seeds to a small blender. Blend until completely smooth. Stir in the poppy seeds until well combined. Set aside until ready to use.
Heat a pot of water on the stove top to boiling and add the broccoli florets to quickly blanch. Leave the florets in the boiling water just for 30 seconds or so. Strain, and immediately rinse with cold water. Allow broccoli to dry to pat it dry with a paper towel
Transfer the broccoli to a large mixing bowl, along with the remaining ingredients for the salad. Pour in the lemon poppy seed dressing and toss everything together until well combined. Taste the broccoli salad for flavor and add more sea salt, and/or lemon juice to taste.
