• Ingredients
  1. 2 pounds large shrimp, shelled and deveined
  2. 1/4 cup fresh grapefruit juice
  3. 1 tablespoon fresh lime juice
  4. 1 tablespoon cider vinegar
  5. 1/4 teaspoon dried oregano, preferably Mexican
  6. Salt and freshly ground pepper
  7. 6 medium tomatoes, thinly sliced
  8. 2 ripe Hass avocados—halved, peeled and sliced crosswise 1/4 inch thick
  9. 1 medium red onion, thinly sliced
  10. Extra-virgin olive oil, for drizzling

Directions

1. In a large saucepan of boiling salted water, cook the shrimp until loosely curled and just cooked through, about 2 minutes. Drain well; transfer to a large bowl and let cool slightly.
2. In a small bowl, combine the grapefruit and lime juices, vinegar and oregano and season with salt and pepper.
3. Add 2 tablespoons of the citrus dressing to the shrimp, toss well and season with salt and pepper. Season the tomatoes and avocado slices with salt and pepper and arrange on a platter with the onion, alternating and overlapping the slices. Spoon the remaining citrus dressing over the salad and top with the shrimp. Drizzle olive oil over all and serve immediately.
