1. Cook Ginger Rice
Trim and discard skin of ginger. In a medium pot, combine rice, whole ginger knob, 1 1/2 cups water, and 1/2 teaspoon salt and bring to a boil. Stir once, then reduce heat to medium low, cover pot, and simmer until water is fully absorbed, about 10-12 minutes. Remove pot from heat and let stand, covered, for ten minutes. Fluff rice with a fork, then cover again to keep warm until ready to serve.
2. Prepare Ingredients
While rice cooks, rinse all produce. Pick cilantro leaves, discard stems. Pat lettuce dry with paper towel and separate large leaves for wraps. Trim scallions and cut into 1-inch pieces, keeping whites and light greens separate from dark greens. Roughly chop cashews and dates. Thinly slice garlic.
3. Cook Chicken
Heat 1 tablespoon canola oil in a large pan over medium-high heat. When oil is shimmering, add chicken and season with salt and pepper as desired. Cook, breaking up, until browned, about 5 minutes. Using a slotted spoon, transfer chicken to a bowl. Wipe pan clean to use in next step.
4. Make Sauce
Heat pan from chicken over medium heat with 2 tablespoons canola oil. When oil is shimmering, add crushed red pepper, cashews, garlic, and scallion whites and light greens. Saute, stirring about 4-5 minutes. Add mirin, soy sauce, dates, and 2/3 cup water. Increase heat to medium-high. Cook, stirring, until sauce has thickened, about 5-7 minutes. Add Thai chili garlic sauce to taste (optional).
5. Finish Chicken
Return chicken to pan with sauce, keep at medium-high heat, stir to coat and warm, about 1-2 minutes. Remove pan from heat. Add salt and pepper to taste.
6. Plate Lettuce Wraps
Remove and discard whole ginger knob from pot with rice. Divide lettuce wraps among serving plates and top with rice and chicken. Garnish with cilantro and scallion dark greens. Enjoy!
