Take one lemon and cut out the segments (see below note), setting aside to toss in salad
Juice the other lemon(s) (I got almost a half cup (3/8th's cup) of lemon juice from the one, which was enough)
Pour juice and the other ingredients in a small food processor, with the exception of the oil.
Drizzle the oil in slowly while whizzing to emulsify.
Toss the segments in your salad along with the dressing.
