Preheat oven to 400°F. Toss diced gold potatoes with a tiny drizzle of oil and a pinch of salt; roast on a baking sheet for 15-20 minutes until tender and golden.
In a small bowl, whisk together lime juice, lime zest, red pepper flakes, garlic powder, salt, and pepper to create the marinade.
Coat the chicken thighs thoroughly in the lime-spice mixture and let them marinate for at least 10 minutes at room temperature.
Heat a non-stick skillet over medium-high heat with the remaining olive oil. Sear the chicken thighs for 5-6 minutes per side until the internal temperature reaches 165°F.
While the chicken is cooking, bring water to a boil in a small saucepan, stir in the couscous, cover, and remove from heat. Let it sit for 5 minutes, then fluff with a fork.
Assemble the bowl by layering the fluffy couscous at the base, followed by the roasted potatoes and fresh shredded carrots.
Slice the chicken thighs into strips and place them on top of the bowl, then garnish generously with fresh cilantro and an extra squeeze of lime if desired.
