In a large bowl, toss together the lettuce, strawberries, clementines, and dried cranberries.
For the dressing: combine all of the ingredients together except for the oil in a food processor or blender. Blend until all ingredients are well incorporated and zest has been broken down. Add in the oil in a slow, steady stream and pulse until just combined and emulsified. Avoid blending the oil in for an extended period of time as it can make the oil taste metallic.
Right before enjoying, add the dressing (add to taste -- you may not need/want it all), pistachios, and feta cheese. Do not add pistachios, cheese, or dressing to any salad you'll have leftover. (It doesn't sit/store well together.) Toss and enjoy immediately.
Notes
*With all salads, adjust the amount of fixings and how much dressing you use to your personal preference!
