Mix blueberries, lemon juice, olive oil, & honey in Magic Bullet until pureed.
Taste-test and decide if you want to add Splenda. (I usually add the full tablespoon). Add a dash of salt and pepper. Blend.
Add approximately 1 & 1/2 tsp. poppy seeds, if desired.
Notes
Note: if you don’t have a Magic Bullet, I recommend making a double or trip batch of dressing in regular blender. Then freeze whatever won’t be used in next 2-3 days. I freeze it in little 1/4 C. containers, then I have dressing for a couple of weeks!
