COCONUT BASMATI RICE: Get the rice started first (if making). Combine 1 cup basmati rice, 1 and 1/2 cups full-fat coconut milk, 1/2 cup water, and 1/2 teaspoon salt (or to taste). Stir and place over high heat. Once boiling, reduce the heat to low and cover the rice. Allow to simmer for 13-18 minutes or until liquid is absorbed. Remove from heat, keep covered, and let stand for 10-15 minutes; don't rush or it will be sticky! Fluff the rice with a fork and then add in the zest and juice of one lime. Stir and evenly divide onto plates.
SAUCE: In a small bowl, whip together the sauce ingredients: add the 2 tablespoons soy sauce, 1 teaspoon lime zest, 2 tablespoons lime juice, 1 tablespoon Sambal Oelek (See Note 1), 1 tablespoon brown sugar, and 1/2 teaspoon salt (or to taste; it will depend on the saltiness of the soy sauce, but note that ground chicken does need a good amount of seasoning). Stir to combine.
TOPPINGS: Prep the toppings next: thinly slice the Persian cucumbers and place in a medium sized bowl. Add the 1 tablespoon rice vinegar, 1 tablespoon olive oil, 1 tablespoon lime juice, 1/4 teaspoon salt, and 1/4 teaspoon pepper to the cucumbers. Stir and give the mixture a few more stirs while cooking the ground chicken. Give the herbs a quick coarse chop and place in a bowl (See Note 2).
LARB MEAT: Finally, prepare the meat portion. Add 1 and 1/2 tablespoons coconut oil to a large cast iron skillet and melt over medium high heat. Once shimmering, add in the 2 teaspoons minced garlic, 1 tablespoon minced ginger, and 1 cup of thinly sliced green onions. Sauté for 3-4 minutes or until fragrant and tender. Add in the ground chicken. Make sure to really break up the ground chicken with a wooden spoon so there are no large clumps. Sauté for 7-9 minutes (breaking up/stirring almost constantly) or until mostly cooked through and white all over. Drain off any accumulated liquid and return skillet to medium high heat. Pour the prepared sauce over the chicken and cook for another 2-3 minutes or until chicken is fully cooked (no pink remains) and sauce is coating everything. Remove from heat.
SERVE: Serve appetizer style with lettuce leaves, larb meat, coconut lime rice, a bowl with the herbs, and the cucumbers. Either layer everything in a bowl or on a plate (coconut lime rice, larb meat, chopped herbs, cucumbers) or fill up lettuce wraps. Enjoy immediately.
