Toss the sliced cucumbers, radish, and green onion together in a mixing bowl with the lime juice, tahini, and chili crunch. Refrigerate until ready to serve.
Heat the olive oil in a large pan over medium-high heat.
Once hot, add the brussels sprouts and toss to coat in the oil. Add a generous pinch of salt and pepper. Cook for 2-3 minutes until the sprouts begin to slightly char in spots. Stir and cook another 2-3 minutes to pick up more color before transferring to a bowl. Set aside.
Add the ground turkey to the pan and cook for 2-3 minutes on one side until golden brown before breaking apart to fully cook.
Once the turkey is cooked and crumbled, add the thinly sliced white part of a green onion and ginger to the pan. Cook until fragrant, about 1 minute.
Add the brussels sprouts back to the pan with the cooked turkey, followed by the sweet chili sauce and soy sauce. Stir everything together and cook for 30-60 seconds to warm everything through.
Salt to taste and serve over rice with the cucumber salad. Garnish with the remaining sliced green onion, toasted sesame seeds, a squeeze of lime juice, and additional sweet chili sauce, if desired.
