Pickle Veggies: In a large bowl, mix carrots, radish, vinegar, sugar, and salt. Let sit at room temp for 1 hour (or until ready to eat), stirring gently every 15–20 minutes.
Prepare rice according to package directions. Set aside once cooked.
Zest and juice the limes to get 1/4 tsp zest and 3 tbsp juice. In a bowl, whisk together mayo, lime zest, lime juice, sugar, and Sriracha until smooth. Season to taste; I add 1/4 tsp salt. Cover and chill.
Heat sesame oil in a large pan over medium-high heat. Add pork, salt, and pepper. Break into small pieces and cook for 7–9 minutes or until browned. Add green onions and cook 2–3 more minutes, stirring often. Stir in garlic and cook 1 more minute. Add fish sauce, Sriracha, and sugar. Stir well, until slightly caramelized. Remove from heat, and stir in basil.
Divide rice between 4 bowls. Top with pork. Use a slotted spoon to add pickled veggies, then add cucumbers. Drizzle with sauce and finish with any toppings you like.

Notes
Storage: Keep rice and meat in the fridge for 3-5 days. Pickled veggies last up to a week in their liquid, and the sauce keeps for 5 days. Add fresh toppings just before serving.
