Add ingredients to a food processor then process until smooth. Place shrimp in a large ziplock bag or glass container then add 3 Tablespoons of the dressing and marinate in the refrigerator for 10 minutes (no longer.) Reserve the remaining dressing for the salad dressing.
For the salad:
Spray a large skillet with extra virgin olive oil or nonstick spray then saute the marinated shrimp for 1-2 minutes a side, or until just barely cooked through. Set shrimp aside to cool slightly. Discard remaining marinade.
Divide lettuce and red cabbage between plates then top with avocados, tomatoes, sauted shrimp, and crushed tortilla chips. Sprinkle with sea salt, if desired, then drizzle dressing on top and serve.
