Bring 2 cups of water to a boil in a small saucepan.
Add jasmine rice and kosher salt.
Reduce heat to low, cover, and simmer for 12–15 minutes until the water is absorbed.
Remove from heat and stir in sesame seeds and sesame oil.
Allow the rice to cool while preparing the chicken.
Season the chicken thighs generously with kosher salt and black pepper.
In a small bowl, whisk together maple syrup, olive oil, lemon juice, lemon zest, and minced garlic.
Pour the marinade over the chicken and coat evenly.
Heat a large skillet over medium heat.
Cook the chicken thighs for 7–9 minutes per side until golden brown and fully cooked.
Transfer the chicken to a plate, cover loosely, and rest for 5 minutes.
Slice the chicken into strips.
Divide the sesame rice evenly among four meal prep containers.
Top each container with sliced chicken and cucumber.
Garnish with extra sesame seeds, fresh herbs, and lemon wedges if desired.
Drizzle lightly with sesame oil before serving.
