1/2 cup fresh lime juice
1/2 tablespoons fish sauce
2 teaspoons white sugar
cloves garlic, crushed
1 red grapefruit, peeled and sectioned
2 cups shelled cooked tiny shrimp, thawed if frozen
2 cups shredded precooked chicken breast meat
1 1/2 cups shredded coconut meat, unsweetened
6 shallots, thinly sliced
1 teaspoon chopped red chile pepper
1/2 cup fresh mint leaves
1 1/2 tablespoons finely chopped fresh cilantro
1 head iceberg lettuce, shredded
Make the dressing by whisking together the lime juice, fish sauce, sugar, and garlic in a bowl.
Toss together the sectioned grapefruit, shrimp, chicken breast, coconut, shallots, chile pepper, mint, and cilantro in a large bowl. Drizzle approximately 3/4 of the dressing into the grapefruit mixture and toss to combine. Combine the remaining dressing with the shredded lettuce in a separate bowl shortly before serving.
Arrange the lettuce on a large platter. Layer the grapefruit mixture on top of the lettuce.
